Sitting Up

Lily

So my baby will be five months in a week, but he was born 2 months early so I think he’s around 3 months adjusted

Anyways I was wondering when have y’all’s baby started to sit up or raise/control their necks/heads?

We do several forms of tummy time and other exercises but he still hasn’t been able to sit or maintain his head up

He’ll lift his head up only for several seconds when he’s on his tummy but that’s it
