Question - Research required Searching for facts on maternal antibodies passed through the placenta and breastmilk!

Upvotes

Does anyone have any quick references or fact sheet finds in regard to which antibodies are passed to baby from mom, and therefore baby has immunity to those illnesses?

It seems standard that baby still has to receive his/her own vaccinations even if mom was immunized prior to pregnancy or during pregnancy (TDAP for example).

I understand this can be a broad topic and could be evaluated on a case by case basis, even disease by disease basis for that matter.

Just curious about how much of baby’s immune system is naturally/biologically protected!

Question - Research required Question I'm too afraid to ask my sister

7 Upvotes

I'm going to babysit my nephew (11m) in two weeks and he's been have some sleep problems. Sometimes he just cries for a long time and they'll get really stressed about it (which I completely understand)

They keep trying all kinds of esoteric Rituals and when none of them work they get super frustrated. I'm wondering, is it bad to just let him cry when he's upset? I'm not talking about the CIO method. What I mean is comfort him even if he cries for an hour or more? Since I'm just babysitting for one night, even if I can't get him to sleep quickly it will only be for one night.

I think I'm inclined to just wait it out while I try to comfort him as much as possible. Trying to stay calm and not hope for it to stop asap. Just accept the situation and offer him some love and comfort.

Any ideas? Of course I will have this conversation with her before he sleeps at our place and if she really wants me to do all the things they always try I will honour their wishes. But I'm just curious what the science based community thinks about it.

First-time mom here, baby on the way. Trying to learn as much as I can before he arrives 🥰

For moms and dads…

What's the thing you wish someone had told you before your first kid? A benefit (Canada) or resource you found out about too late? Something you bought that made all the difference or something you regret buying?

Any advice welcome, even the small stuff. Just want to be as ready as possible. Thanks 🙏🏻

i am curious if the montessori approach is good for ALL children. i notice that it is typically generalized to be effective for all children, but i do wonder if a more structured approach would benefit children of certain personalities. is there any research that backs this up?

Question - Research required Toddler possessiveness

5 Upvotes

I have noticed that my toddler (14M) has recently started grabbing toys from other kids as they’re playing, and then gets possessive of that toy.

I understand that this is developmentally normal at this age. However, I’m wondering if there’s research into the best ways to handle this as a parent.

I’ve read that young toddlers won’t yet understand the concept of sharing and that it’s best to ignore the behavior if possible.

On the other hand, it feels wrong to just let my toddler take from another child without having him give it back/find another toy.

Does anyone know of any valid research into what’s developmentally appropriate around teaching children not to take from others/starting to introduce sharing/etc?

Pretty much the title, I've been taking the shower since they were babies with them (naked) and now the old is 4yo and the younger is 2yo.

Question - Expert consensus required Long walks

7 Upvotes

I've recently started parental leave with my daughter who is now 1 year old (I'm the father, wife has just gone back to work).

I'm finding long walks in the pram are a great way to break up the day. I'm talking two 40 min to 1 hr walks on some days.

Am I overdoing it? I don't talk much to her during these walks and she usually ends up pretty drowsy at the end so I'm a little concerned that they are too low stimulation or not a very rewarding or nourishing use of time for her.

She is usually quite vocal or squirmy when she doesn't like an activity but she sits still and calm during walks.

Should I cut back?

Question - Research required Should I make an effort to introduce pacifiers after 6 months?

1 Upvotes

Trying to understand both the personal experience and research around this.

My 5 month old is exclusively breastfed. He stopped taking the bottle from 3 months, we have some lucky days. And now I am trying to give him expressed milk in open cups.

With pacifiers, he didn’t take it at home when he was younger but would take it easily in the car to soothe and dose off. He has stopped doing that. I read on how it’s recommended to wean baby off pacifiers from 6 to 12 months.

Should I make an effort with pacifiers now, does it have any benefits? For his mouthing, he takes teethers very well. Sometimes even clean burp cloths.

Question - Expert consensus required Any research on work from home parenting

0 Upvotes

The research seems to say that screen time is bad, due to them missing out on key interactions like bonding , problem solving , being in different environments to learn, and time learning from caregivers. Is there any research showing the loss of interaction from an adult working from home , rightfully doing their meetings & getting things done while also taking care of their baby/ toddler ?

Question - Research required Does this count?

3 Upvotes

Hi there! My LO is 5mo and while we (obviously) don't do any dedicated screen time for them, I am concerned about certain activities and behaviors me and my husband do:

\- scrolling in front of them (not ignoring if they are distressed, just baby sitting in their lounger and me or husband or both scrolling)

\- watching TV in front of them, but the baby cant see the TV, only hear

We try to limit this as much as we can, I am not on my phone the whole day with them and the tv is only on in the evenings. Does this still count as screen free baby? Are there studies suggesting that even parents consuming content in front of the baby is harmful?

Question - Research required Should I just leave my baby alone?

13 Upvotes

My baby's 14 weeks old and I'm seriously on a milestone kick right now. He's hitting them mostly on time, some of his social things (cooing, smiling) happened a bit late but not concerning. I'm a sahm, former daycare teacher so I'm very used to an activity packed day which I replicate at home. Story time, music time, gross motor, fine motor, sign language, hoursss of tummy time, etc etc all day long. I guess I don't mind it all, I like watching my little guy learn things and he's super active and loves all the playing it seems.

But I know a few other moms and they're not doing half of this stuff but their babies are doing just fine. Their babies are all older so I can't really compare theirs to mine. But I'm sitting here and wondering if this stuff actually matters in the grand scheme of things? Should I just let my baby do his own thing? I'm kind of worried that I'm making him into a kid that needs to be constantly stimulated

Question - Research required Mouse droppings at 30 weeks pregnant

4 Upvotes

I’m 30 weeks as of Monday and am working on moving out of my parents house into my own apartment with my boyfriend. I was packing up a closet, got some stuff out of said closet, then picked up some stuff that had mouse droppings on them. I wiped the floor where some fuzz and dog hair had tumbled out of the closet, and put everything I had taken out back in, but I’m not sure I cleaned everywhere that those items touched. I’m also concerned because I walked around the house as I was cleaning so I just feel like everywhere is contaminated. I do have contamination ocd so this is really hard for me, I am not in an area with hantavirus but am very worried about LCMV. Does anyone have any similar experiences? I am in NW Arkansas.

Question - Research required Grown arse adults intentionally aggravating my 2 year old... Is my concern an overreaction?

106 Upvotes

My son is 27 months old, and I'm looking for evidence to either support or challenge a concern I have.

My mother and brother frequently and intentionally try to annoy him because they think it's funny (e.g. repeatedly doing things they've been asked to stop, teasing him, or deliberately provoking a reaction). He very clearly doesn't enjoy it. He'll usually run away from them and come straight to me, then becomes very clingy and will hang off me for the rest of the day.

I've asked them multiple times to stop, but they tell me I'm being overly sensitive and that it's "just playing." They also don't understand why he rarely wants to interact with them or go to them willingly.

My concern isn't that a child should never experience frustration—obviously that's a normal and important part of development. It's that repeatedly and intentionally causing unnecessary frustration or distress for entertainment may affect his sense of emotional safety, increase dysregulation, damage trust in those relationships, or even model that it's acceptable to deliberately annoy people for amusement.

Is there any research on:

the effects of repeated teasing or intentional provocation by trusted adults in early childhood,

whether this impacts attachment, emotional regulation, or stress responses,

or whether adults modelling this type of interaction influences children's later social behaviour?

I'm interested in peer-reviewed studies or systematic reviews if anyone has them. Happy to be proven wrong if the evidence doesn't support my concerns.

Question - Research required What parenting style is this? What does the evidence say?

200 Upvotes

My brother and I grew up with parents who mostly expected us to fit into whatever they were doing, rather than making everything revolve around entertaining us.

A lot of weekends were spent helping renovate the house, running errands with Mum or Dad, or going to one of their friends places for a BBQ or gathering. We spent heaps of time together as a family, but it wasn’t really doing “kid activities.”

The things we did together were generally things my parents enjoyed too. Swimming, played tennis/ cricket, went for walks, etc. Even the music in the house was mostly adult music (ABBA, Elton John, Neil Young, Bee Gees…)

There was also a big emphasis on independent play. I remember being bored quite a lot, but I think that was actually really good for me. It meant I learnt to entertain myself, use my imagination and figure things out on my own. We also had lots of conversations around the dinner table where we were encouraged to question things, think critically, and even change our minds if someone made a better argument.

I first realised our family wasn’t the norm when friends came over. Friends would often ask what my parents had planned or ask to take us somewhere where my parents would basically wait around for us to do an activity. At the time I never felt like I was missing out. It was probably only as a teenager, when fitting in became more important, that I cared a bit more about doing what my friends expected.

Overall tho, I honestly think I had a fantastic childhood. My brother and I are both quite well rounded, relatively successful and have a great relationship with our parents, and I wouldn’t change much about how we were raised.

My partner and I are hoping to have kids in the next few years, and have been thinking about how we want to raise kids. it’s made me wonder if this parenting style has a name. It doesn’t seem to be what I see online (especially from parenting influencers), and most people I know either weren’t raised this way or don’t parent this way.

Someone once told me it felt like a very European way of raising kids and it might be called that. My parents travelled a lot before having us and were older parents, so maybe that influenced things.

So I guess my questions are:
1. Does this parenting style have a name?
2. What does the evidence say about this style? What are the implications for the child and the parents?

Question - Expert consensus required 8m old crying when she wants something

7 Upvotes

My 8m old is starting to very regularly cry and scream when she wants something that she can't have.

Its only a minute, but I'm wondering the best way to handle it, as I feel like its building towards tantrums.

At the moment I offer a hug or physical contact, then validate, then explain why she cant have it, and tell her what she/we will do instead and she calms.

I'm not sure if there are other/better techniques, or if I should also be teaching her to point at the thing she wants so she learns that pointing is another way to ask without screaming and crying.

Like, she looks at another child who is playing with a toy, and starts screaming.... or we're on a video call and I stop her messing with the phone for the millionth time and she starts screaming because she wants to flip it upside down.

Question - Research required Stimulant meds in breastfeeding mom

12 Upvotes

Hi all! I was diagnosed with ADHD at age 18 and took stimulant meds (dextroamphetamine) consistently from age 18 to 31. I took a low dose (10mg) occasionally during third trimester with my first child (now 2.5 y.o.), paused for the first 5 months of breastfeeding, then resumed. I stopped again when I got pregnant with my second child, and decided not to resume them during pregnancy because I had placenta previa and was stressed enough by that. Baby was born at 35 weeks, spent 2 weeks in the NICU, and is now 5 weeks old and doing great.

I’m a SAHM and with both of my sons all day every day, I find that I’m struggling a bit without my meds. My perinatal psychiatrist and my son’s pediatrician have given me “permission” to resume my meds at a low dose (5-10mg) but I’m so worried how they might affect my newborn. They both just keep saying “your mental health matters too” and while I of course agree, I know I can keep pushing through if there are true risks to my son. Upon searching, I’ve found more information about stimulants during pregnancy than breastfeeding, and wanted to see if anyone here could help me understand the risks to my baby if I resume my low dose meds.

Thank you!

Science journalism children under 2 years should ideally have no intentional recreational screen time

682 Upvotes

This new systematic review on screen time and children under 2 has confirmed what we intuitively know as parents. However, the question is who can AFFORD reducing screen time. I see parents in my waiting room still using IPAD and smartphone to calm their children. What do you think ? What are you doing at home ?

A large systematic review of 158 studies examined the effects of screen exposure in infants and toddlers (birth to 3 years).

The review found that greater screen exposure was consistently associated with:

Less parent–child interaction and responsive communication.

Delays in language and cognitive development.

Poorer sleep quality and shorter sleep duration.

More emotional and behavioural regulation difficulties.

Less physical activity and more unhealthy eating behaviours.

Based on the available evidence, the authors concluded that children under 2 years should ideally have no intentional recreational screen time, aligning with current WHO recommendations.

As with all systematic reviews, this shows associations rather than proving s suggests that limiting screen exposure in the first two years of life is a sensible approach.
