Longest stretch of sleep?

Jenni

What is the longest stretch of sleep everyone’s babies are getting (night or day)? My LO just slept from 5:30am to 10:30am and I feel like I should have let her keep going because she’s 7 weeks old and gaining weight appropriately but she was grunting/moaning a lot so I scooped her up. Do your babies also grunt/moan in their sleep? Sometimes she even seems like she’s crying but her eyes remain closed, and then she’ll just stop and look sound asleep. How do I know when to pick her up?
