Need another layer??

*please no judgement or shaming against bed sharing*

My son is 5 months old and bedshares with us and I’ve kept his pjs light to avoid overheating. He wears long sleeve footie pjs and doesn’t get covers. Normally it’s been fine, but the last 2 mornings he’s waking up with cold hands and when we undo his pjs to change his diaper, his legs and feet are a little cold too.

Should I put him in the zipadee zip overnight plus the long sleeve footie pjs? I want him to be warm but not over heated
