Our son is 15 months old. He had several issues as an infant with drinking milk and poor wieght gain. He also had severe reflux which needed medication. He refused to eat puree and took a long time to eat solids. He eats kind of ok now but very small bites and takes forever. He does not eat a lot. Took him to an ent specialist and has been followed by several doctors but I think that be has a lip tie, I often see his upper lip kind of pulling in sometimes when he moves his mouth . Be has a gap between his teeth. Should I take him to another specialist , I toom him when he was 7 months to be checked specifically for tounge tie and lip tie as she would not eat and was told that he does not have a tie. But now I am second guessing it as I can see something between his teeth
