I've been so lucky to be able to co-sleep and put her in her crib also.. She has no problems switching between either. She falls asleep at 10pm, and she doesn't wake up until 10am! I knock out at 11:30 (usually) and wake up when Shes waking up! Wonder how I know she's up? Her bottle is empty in the morning obviously & she tries drinking milk and when none comes out, she stands up & throws it out her crib onto the floor.. I get up real quick. Haha. That's her saying "yo I need more milk" lmao
