Finally rolled from back to belly (at least I think so, my husband said he did). He was getting to his belly before but his arms were stuck, I don't know if my husband noticed if he was fully there.
Reaches arms out when he wants to be picked up.
Screams bloody murder 30min-hour after he's gone to bed.
You guys have mostly older LO's, how did you survive the 4 mo sleep regression?
