My little girl is one month today. She hit her birth weight at her two week appt and is now up another pound.

I have been setting an alarm for 5 hours to wake her to feed her during her last feeding of the night, per my LC one five hour stretch is great. Well she has slept 5 hours a night, followed by another 2-4 hour chunk for a week straight. I'm fighting a little cold and forgot to set the alarm last night. She slept for 6 hours before waking me up. Our next dr appt is not till 2 months, and LC appointment is not for another week and a half. So I thought I would ask you all. When did your newborn start sleeping in longer stretches? At what age is it ok to just let them sleep? I've been reading old posts and read several books and everyone has a different opinion.
