Day time versus night time sleep

Kate • Momma to Cameryn 💕 and baby girl #2 due 7/17/22 🥰

Just curious what you mammas are doing. I took the takingcarababies newborn sleep class and she says to wake your LO every 2.5-3 hours during the day for feedings to try and get as many calories in during the day in hopes to get longer stretches of sleep throughout the night. I’ve been doing this, but wonder if waking her during the day gets her in the habit of being up every three hours. She hasn’t really slept longer than that at night. Part of me wonders if I let her sleep for longer stretches during the day she may get into a routine of it and sleep longer at night as well. What are you all doing?
