Fidgety baby

Po

Does anyone else’s 6 month old baby just squirm all night? I will feed him and then 2 hours later he will partially wake up moaning because he won’t stay still! He will knock his dummy out and not stop rubbing his face. I’m not sure if it’s separation anxiety because once I pick him up, 10 minutes later he will calm down, I put him back down and he will start wriggling again.

Any tips or ideas why??
