Baby sleep thru night at 6 weeks?

Janelle

My son seems to be a good sleeper and is sleeping less during the day and more soundly at night. My doc said he doesn't like to let babies sleep through the night until they're up to 11 lbs. Our son was 9 lbs. 12 oz last doc visit.

I've seen other people say they do it, just curious what yall do out here in glow land?
