My daughter went through a period of time where she chewed on her tongue a lot. She is on the spectrum and I believe this was her stimming. It's hard to say anything definitely without meeting the child, but it's a possibility.

Some of the behaviour you have mentioned could mean that the child has developmental delay. Things like flapping of hands and poor eye contact. It is best to get the hold assessed at an Early intervention centre or with a child psychiatrist. Remember earlier you diagnose and provide therapy , you will see faster improvement.
