10 month old waving hands?

[Newmum26]

My 10 month old has started to wave his hands when he's had enough, so if he doesn't want any more dinner he waves his hands in front of him and frowns at me.
He's also a few times been holding his arm up and studying his hand for a few seconds at a time but then gets distracted by me if I take his mind off it.
He's my first baby so my question is are these Typically developmental traits and behaviours in a baby as when I type in online it says they can be signs of autism? But then it says normal developing babies display autistic behaviour I'm so confused lol. X

You’ve posted on this topic before. The advice you were given on your previous threads still stands.

Is it possible that you have some underlying issue or reason to worry excessively that your child might have autism? From what you’ve posted now and before it sounds as though you have a normally-developing child.

Sounds like normal 10 month old behaviour. Hands are mesmerising at that age

Completely normal for a 10 month old
