Yet another sleep related post:
So I have to push the reset button on my baby. His feet are hanging off the RnP and his head is an inch away from the top, yet he refuses to sleep anywhere else besides there, the swing, or car seat. We have a bedtime routine in place. Bath, lotion, pajamas, sleep sack, book, nurse, bed. As soon as he gets into the crib, he rolls onto his belly, his arms straighten, and he starts crying. I pick him up, comfort him, put him back on his back, he rolls again.
I've stopped picking him up and now I just pat his back until he figures out how to relax his arms to fall asleep. There is a crib wedge in there but he refuses to lie on his back so I'm going to take it out. We've tried the crib for naps and it's the same story. Our sound machine is on white noise as well. I've even tried the projection turtle but he's not on his back to enjoy the show. I'm not opposed to CIO and my pediatrician said that he would try that next. He's now on a strike from all naps and is over exhausted unless we put him in the car seat, RnP, or swing. He won't even sleep on me!
HELP

Re: Reset my LO
My LO was doing the whole rolling onto the belly and crying thing too. I couldn't take the lack of sleep so I put the sleepsuit on him, and it works.
At least you would get LO out of the RNP...
I think I'm out of advice. I tried weaning my guy out of the sleepsuit about a week ago. The first night I put him down without it (he was mostly asleep but not in deep sleep) and after a lot of rolling and crying, I ended up holding the side of his PJ's back so he couldn't roll onto his tummy. He was basically stuck on his side because I wouldn't let him go far enough to get to his stomach. I held onto the PJ's until he fell asleep.
However, after several wake ups over the next three nights, I've completely given up and am waiting for winter break when I don't have to function for work.
Good luck!! I should probably just second what Shoogars said - just don't give up until it works.
