Bigger baby sleeps more??

Me

Any mamas with bigger babies? Mine was born at 8 lbs 13 oz and weighed 8 and 5 a week ago. He was 5 days old.

Now he’s 12 days old and sleeping more-3.5 hours ish before wanting to eat again. He is breastfeeding 80% ish. Anyone else? I know he should eat more but he fills up and falls asleep. I’m really not concerned about his growth. We don’t have another ped appointment until next week. 🤷🏼‍♀️
