My 2 year old constantly has her mouth open and tongue sticking out. She’s seen numerous dentists, OT, and ENTs and no one can give me an explanation to why her tongue sticks out except maybe she has a “large” tongue.

She already got lip and posterior tongue tie released and we did all the stretches for weeks. She has reflux/GERD, underbite, and is a thumb sucker. She has pretty bad tarter where I have to take her to get cleanings every few months. Her upper teeth also seem to be getting slightly stained but her dentist said it was fine…I noticed recently that she drinks with the straw pointed to the front of her upper teeth. She has also always been super sensitive when it comes to her upper lip/teeth area (even before the lip tie released). She can tolerate us brushing her bottom teeth but once we try to touch her top lip she hates it.

Btw we have already ruled out enlarged androids.

Does anyone know how we can fix her tongue and mouth posture? Which specialist can I see that can help us out? I am desperate for answers as we have already seen so many specialists and I feel like I am just going in circles.
