Baby hitting

Collette

I know it may just be developmental stage and experimenting with his body, but I feel like my baby understands what he is doing and hits out of frustration. I’m sure that is because he’s trying to communicate or not able to do some skill yet that he wants to but still... he swats at us often and is visibly upset when doing it.

Is this normal??

I’m not sure how to help him because I don’t always know why. Working on sign language.
