^^^ this!
DD was the same as our little one for the first 9 weeks then bammo, she started sleeping again 6 months ago
She was one of the few that thrived on 6-7 feeds a day. So few feeds! Honestly if someone told me she could feed so little now, I think my jaw would hit the floor. I had to offer feeds every 3-4 hours to even get her to show an interest. DS feeds about 3 billion times in 24 hours, he lets you know clearly when he is hungry. Other end of the scale!

Agree on the resettling with a dummy though, I wouldn't be doing it after such a long nap. If she's stirring then it might be time to wake her. There are generally signs of hunger before bubs get to the screaming stage
