DS wil not sleep more than 2 hrs at night or 20 mins during the day in his crib. When he was first born he would sleep in it, but it would take us 1.5 hrs to get him back to sleep after waking for a feeding. We suspected reflux and I hurt my back which made it impossible for me to pick him up/put him down in the crib so we moved him to the RNP. He immediately started sleeping better and would go right back to sleep after eating at night. He essentially will only nap in his swing.
Tell me how you transitioned your little one from the RNP to the crib. I'd love to hear different methods as what I've tried so far isn't working.
