My son is nearly 7 weeks and last night he had a feed at 7pm then we put him to bed. I was woken up at about half 12 to him kind of stirring, rolling about, waving hands etc and his eyes were open so I went to prepare his bottle except when I came back he was fast asleep again! And this behaviour has continued all night so he's not had any feeds and I'm reluctant to let him go 12 hours but equally I'm aware of never wake a sleeping baby. Every time I think he's awake within the same minute he's fast asleep again so I don't know if it's active sleeping?
He didn't really nap much during the day so I don't know if he's making up for it and he had a lot of feeds during the day. He's on 5oz and nearly 11lb.
