My son was doing great sleeping. He was sleeping 5-6 hours (even up to 8 hours) in a row starting from 4 weeks old. We stayed with my family on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and had him cosleep between us in the bed, which we never do. He slept great, 8 hours in a row. (I had to wake up and pump, but he slept through it.) Now, we're back home, and he's been having trouble sleeping in his bassinet. So we've been cosleeping again because he wakes up when we put him in his bassinet, and we eventually get tired and just give up and put him in the bed. I want him to go back to the bassinet, but he wakes up every time I set him down, even if he's been asleep for a while and it's driving me and my partner nuts! Help please! UPDATE: My son stayed up later last night, but he slept in the bassinet! I just put him back in it after waking up to nurse, and he wiggled a little, but didn't wake up! I was so worried that it would be difficult, but he wasn't fussy at all! Thanks for the support ladies! Next time we visit family, I'm definitely bringing the pack and play to avoid a repeat of this situation. The only reason we didn't bring it this time was because our car was too full with Xmas presents, and it wouldn't fit.
