Signs of Autisim in kids?

My son will be 2 in November. He toe walks off and on. He stomps around sometimes. He walks flat footed as well. He started walking around 11 months old. Is this normal? I just worry about the association between toe walking and autism. He says a lot of words but they are not clear. For example “bus” is “buh” and “milk” is “millll”. He can’t get the ending of some words. Waves bye bye and says it as well. He does many other things that leads me away from autism but I just worry so much.

I would bring him to a developmental pediatrician and see what they say.

Toe walking by itself isn’t really a big worry bring it up to your pediatrician see what the doctors feelings about it are
