I don't know if the lowering of the mattress caused a sleep regression. I think it was more due to the fact that she was learning to pull up. It was easier when she was just laying there crying. Now, she stands up and bawls her eyes out. And then he plunks down, sometimes hits her head and then starts screaming bloody murder. </p> https://boards.hellobee.com/topic/did-lowering-crib-mattress-affect-los-sleep#post-692341 Thu, 04 Apr 2013 16:05:36 +0000 mamajaja 692341@https://boards.hellobee.com/ <p>LO is 11 months and has been trying to pull up on any and everything so we knew it was time to move her mattress down to the next setting. LO is definitely going through some milestones, wonder week, teething, seperation anxiety, etc (you name it, its all happening right now!), but I also think the lowering of the crib has made putting her into her crib harder, as she definitely fusses more when I'm lowering her into her crib, sometimes to the point where it wakes her up and won't go to sleep!</p> <p>Has this happened to anyone else? </p>
