That looks a lot like a tongue with a tie to me... if your DS is bottle fed, you might not have noticed. And some babies actually manage to BF quite well with tongue tie (my DS did very well at compensating for it up to a certain point, but the colic was terrible due to his latch - so we had it cut).
GPs often don't know what they're looking for with TT- you might need to see a specialist.
My DS used to stick his tongue out and dribble a lot. It is often a sign of low muscle tone around the mouth; children with Down syndrome, who tend to have low tone, often do this. (For clarity, I am not saying that your DS has Down's. Just that he may have a little low tone orally). There is a rare condition that causes a large tongue but I think affected children keep their tongue out all the time from birth?
Oh god now I can't stop worrying,hopefully I get an appointment to the see Gp tomorrow. I'm already worried about stiffness around his knees.Gp notice he wasn't strengthening his legs and that his knees feel stiff. Now I'm wondering if the two are related.
My dh has a big tongue, always visible in old photos!! Be warned he grew to 6'4! Seriously op he is sticking his tongue out simply because he can!! Get him a check up or you worrying will spoil these precious days!!
Not sure what to say here. DD2, now 7, is 100% and probably scary smart (her dad is a Cantab 1st so I take no credit) but as a young baby she often had her tongue partly out and, in the way that some people have big ears, I think her tongue is probably on the large side. And when she was a baby she was exclusively BF because she never mastered bottles and her tongue was often between her lips like a cat flap.
