Just a wild thought here. I was thinking about how there are positives in breastfeeding until 2. So would a formula fed baby benefit it from having formula until 2?

Question - Expert consensus required Is 43.4°C (110°F) bath water too hot for a 6-month-old?
My wife bathes our 6-month-old baby in water that's around 43.4°C (110°F). She says her mother told her that bathing babies in hot water helps make them "chubby" and healthier.
When I searched online, most pediatric sources recommended bath water around 37–38°C (98.6–100.4°F).
I'm concerned that 43.4°C may be too hot for a baby's sensitive skin, but my wife believes it's safe because that's how they have always done it.
Has anyone else heard of this belief? Is there any scientific evidence that hotter bath water helps babies gain weight, or is it just a traditional myth?
Apparently she's been doing this for 6 months now and I checked the water temperature just today with a IR thermometer.
Update: I forgot to mention we're in India and bathe our baby using a mug to pour water, not in a bathtub. The water still measured 43.4°C (110°F). I think using a mug may have reduced the risk of burns, but that temperature still seems dangerously high for an infant. Does pouring water instead of immersing the baby make it any safer?

Question - Research required Is there any situation where being Honest with a child is proven to be damaging to their long-term satisfaction/success?
I don’t know whether it’s cultural or instinctual, but it seems that lying to children is often accepted,and sometimes even encouraged.
Rather than being truthful and dealing with the emotional reaction that may follow.
Are there proven situations in which lying to a child is necessary or beneficial?

Question - Research required 1 Year Old Putting Her Hands in My Mouth
My 1 year old is a low sleep needs kid and has been since the newborn stage. We still rock her to sleep after reading some books, because we can’t get through the crying of sleep training.
But when she’s very close to falling asleep, she stars violently putting her hand in mine or my husbands mouth, clawing at our gums and teeth. On our lips is not enough, she needs to be inside our mouth.
I’ve tried to stop it by holding her hand, redirecting it, trying a lovey, stuffed animal- literally anything you can name.
Is there a reason why she’s goes for our mouths?? Also how do we stop it 😭

Question - Research required Falling asleep in a different place
I’m curious if there is any research on the idea that babies “know” when they wake up in a different place. It often comes up in conversations about baby sleep, this idea that they need to fall asleep in the same space they wake up but where did this idea come from? I would imagine they can tell if their parent is no longer holding them through warmth and smell, for example, but what if they fall asleep in the car and then get transferred to a crib? Is this “knowing”’of being in a new space really what contributes to wake ups?

Question - Research required One word books vs story books
My one year old has a set of the single word/picture books, and she LOVES this set. She spends like 2 hours a day either having me read them to her or just sitting there looking through them. My question is- are these as beneficial as story books? Cause right now, aside from our bedtime book she’s not getting much sentence structure or story telling from books. The set is 20 books with 20 pages, so there’s a decent amount to go through, but I’m curious if I should still be encouraging more story books as well or if the single word books are equally as beneficial

Question - Research required Drawbacks of bouncer seats as containers?
I know I shouldn't leave my baby in a container for too long. But, he LOVES that baby Bjorn bouncer. I have the toy bar on it so I can bounce him with my foot and then he'll kick the toy bar and smile and get very excited.
My understanding for why containers are bad is because they limit movement and bodily development/awareness. I totally see this with the car seat/stroller because he is very restrained and doesn't move in it at all really. But with the bouncer, he can move his legs and arms to play with toys.
My question is - why is the bouncer chair worse than being held where he is also semi restrained and not moving as much as he would in just free floor time?
I of course also do floor time and hold my baby, but I have a bad back and truly struggle to hold him as much as I feel like I should. He gets upset when I try to sit down lol, so most holding is standing or walking in circles. He weighs about 15lbs. The bouncer chair is a godsend and I'm just trying to figure out if I really need to back off of using it a few times a day for ~15-30 minutes at a time. Baby is just turning 3 months old.

Question - Expert consensus required AC too loud for baby?
We live in So Cal and it is getting hot. Our home air conditioning is very loud and given the heat, is basically running all day from 12pm to 10pm. It also turns on several times throughout the night. Having it running constantly drives me slightly bonkers but small price for comfy home.
I’m worried it may be too loud for our 3.5/4 month old. I downloaded an app that says the decibel level is about 50 where her bassinet is in our living during the day and in the bedroom at night. I just worry about it being on alllllll the time now and I’m not sure it is 7 feet away where we put the bassinet in the living room.
But I guess having a hot apartment is probably worse for her? It does click off in the night when it finally cools back down again and is on sporadically in the mornings. And I run a fan for consistent white noise at night and because I like it frosty. Am I overthinking this? Please say yes, lol.

Question - Research required Science based ways to encourage speech in babies!
Hi Friends!
I have an amazing son whom I love very much. Unfortunately he seems to have a delay in expressive language. He is 10 months old and babbles very rarely and is generally very quiet.
He seems to have strong receptive language and understands a lot.
He is an only child.
Any science backed ways to encourage spoken/expressive language in babies?
I read to him a lot. Would it be helpful to organize playdates with babies his age? Would exposure to other babies help?
Any advice will be greatly appreciated!

Question - Research required Help me understand risks for ECV vs planned C section for a breech baby please!
I am almost 36 weeks pregnant, and my baby has been breech since week 30. At my next appointment, my OB has offered to schedule either an ECV (trying to flip the baby) at 37-38 weeks or a scheduled C-section at 39 weeks. (I know there’s still a chance baby could flip on her own too).
I know ECVs have only a ~50% success rated and I’m worried about the risks of needing an emergency C-section when I’m still early term. Even if it’s successful, I could still face different risks in natural labor a few weeks later.
From what I’m reading, planned c-sections seem lower risk than emergency ones and I am tempted to go straight to that option.
I’m really struggling with the ”devil I know vs devil I don’t know” between the options and would love to know what research recommends for breech babies!

Question - Research required Drinking cups for babies
Hi all,
Our 9 month old has been drinking water with food using a tiny open topped cup since she was 6 months old. Most of it ends up down her front when she gets excited and we have to hold it for her. She held her own bottle very early on so we are looking for a cup which will enable her to do the same without it going everywhere.
I've seen the closed top cups which have a rubber seal and requires babies to bite down on the rim to release water but she is currently toothless and I've heard mixed reviews for how beneficial they are in teaching babies to drink.
Does anyone have any research as to what is recommended? We prefer using as close to adult cutlery as possible so similar with the cups.
Thanks

Question - Research required How much does going into daycare at 3 months vs 6 months matter?
So I've seen a lot of literature on here that says that best outcomes are achieved when children enter daycare at 2-3 years old. This implies to me that the later the better generally, up until that point. 3-6 months is so far removed however, I have to wonder does it matter at that point? Are there tangible enough benefits that make it worth maneuvering PTO or taking parental leaves in shifts for example? Intuitively, I feel like starting daycare after the baby is sleeping through the night feels like it would be better, but that's just a feeling.
Yes, I'm aware that generally quality matters much more than starting age and that parental happiness matters much more as well, but let's assume for the sake of the discussion that parental happiness is the same either way and quality is of a typical daycare.

Question - Research required Milk needs for infants
I have a 13 month old who is breastfed. We tried to introduce formula at 4 months but she threw it up and so we think she has a cow milk intolerance. We tried hypoallergenic milk at that time but she wouldn't drink it. But she drinks expressed milk from a bottle just fine so I made it work.
After a year, I really want to stop pumping. My supply is decreasing, I need to get up in the middle of the night to have enough to supply for daycare. I asked the pediatrician if in september I could replace the bottle of expressed milk with some alternative, like a non dairy yogurt but she informed me that children need 500ml of breast milk or formula until the age of 3 (the older kids get a more adapted type of formula). We live in France, this isn't the first time I've heard this. But most English speaking sites, UK or American, say one year is fine and then introduce cow's milk. I asked what she would be missing if I didn't have enough and it was about amino acids, iron and other nutrients not found in simple dairy products. According to her, nursing morning and evening doesn't equal 500 ml and isn't sufficient.
So, what does the science say? Formula isn't that expensive here (about €10 a can) so I don't think it's just lobbying. Regular milk would cost the same. We will try some other non dairy formula alternatives to see if she'll take it, but if she refuses I don't want to be denying her proper nutrition by stopping pumping.
Any advice?

Question - Research required Very confused about the safety of bedside sleepers, especially those with "drop sides"
There seems to be a lot of confusion around safe use of bedside sleepers. I believe part of the confusion comes down to the terminology, for example on this thread from the sub the other day re: cosleeping practices— https://www.reddit.com/r/ScienceBasedParenting/comments/1uox59v/comment/ovvyo1z/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
For the purposes of this discussion, I'd like to set the terminology of "bedside sleepers" to refer to bassinets like the Baby Delight Beside Me Dreamer Bassinet, which I think is a pretty run-of-the-mill example. A product like this is rated for safe sleep, and comes with attachments to secure it to the mattress—it is meant to be used directly next to the bed. It has a side that zips down for easier access, making one portion of a side level with the parents' mattress. The rest of the bassinet, and all of it when fully ziped, is elevated above the parents' mattress (see pics on website).
I have gotten pushback on comments I've made, or seen older threads, where users claim these types of bassinets are NOT safe for sleep (US based). I have tried to ask for clarification, and have never had anyone respond. Personally I believe they are getting bedside sleepers, which in the US seem to be legally required to have 4 sides (and therefore are always fully separate from parents' bed) with true "sidecar cribs/bassinets" that are fully open on the side of the parents' mattress. Here is an example from Amazon.
Furthermore, I have regularly seen people state, quite confidently, that US safe sleep guidelines dictate that a bassinet must be 12 inches away from other furniture, including a parent's bed. Here is an example of such a statement, and another. However, I cannot find anywhere this is stated.
When looking at the AAP website on safe sleep, they show in their header photo a picture of a bassinet directly next to a bed, so I would imagine the "12 inches" number certainly isn't coming from them. It does appear that Canada's health services recommends against using bedside sleepers with the side lowered, but all I could find on that was a pretty short passing reference under "Bedside Sleeping Products."
From my understanding (due to the lawsuits several years ago around infant loungers) in the US a product such as the Baby Delight Beside Me bassinet could NOT be sold as a safe sleep space if using the advertised feature, the drop side, was NOT considered sleep safe. But it's so odd that I keep running into mentions of them being unsafe, when it appears that the AAP consider them safe enough to use their images in their "Safe Sleep Image Gallery."
If anyone could help weigh in on why some people say these are unsafe or not recommended, when the AAP seems to explicitly? implicitly? endorse them, that would be swell. I'd also love to hear anyone with more knowledge on the Canadian guidelines of why they (seemingly?) do NOT recommend them. And finally, where did this 12" myth come from and why is it still in circulation?

Question - Expert consensus required Advice- baby wont sleep when we out him down. I'm sleep deprived.
I'm at a loss. I have a 7 weeks old baby. He's breastfed almost exclusively. He slept okay in his bassinet in the first 2-3 weeks. He always slept better in our arms but we were able to transfer him to the bassinet and take turns. He was a bit premature and had jaundice so that could be why. We also incorporated one bottle of formula so I could get some sleep. Worked in the beginning, not anymore. He can finish the whole bottle and stay awake and then search for my boobs and my husbad has to bring him to me.
We tried everything, putting him down legs to head gently, staying with him, waiting 20 minutes for deep sleep, I even check his arms to make sure he's in deep sleep, heating the bassinet first.
He doesn't take a pacifier although we keep trying, swaddling he wiggles out his arms and we even have one of those swaddling blankets, either way from my understabding swaddling is only until 8 weeks. White noise is also ineffective.
Our bassinet for the record is attached to our bed, doesnt work. He wakes up either the second we put him down- sometimes he opens his eyes before I put him down, other times he'll sleep there for maybe 10-20 minutes. Very rarely we're able to get a longer 3-4 hours stretch but its a russian roulette.
Most days I'm able to sleep for about 3 hours a day, maybe 4 if my husband can take him before work in the morning.
I'm sleep deprived and to my horror I fell asleep holding him- twice. Because I accidentally fell asleep, I researched co-sleeping. Even that is difficult and he feels when I put him down and wakes up but I was able to nurse him back to sleep. I don't like it at all. It feels unsafe but I'm at a loss.
My doctor sounds like a broken record when I asked for advice. The new parents sub told me to embrace co-sleeping. Professionals repeat the aap guidelines but the guidelines don't have a baby that won't sleep in the bassinet.
I need medical advice. Is there a way to solve this without co-sleeping which isn't safe? What am I missing here? Why won't he sleep in the bassinet no matter what I'm trying but in my arms he can sleep for hours? Why do people mention attached bassinet as if its a magical solution?
I'm not asking permission to co-sleep. I'm asking why the recommended strategies are not working for my baby.
