LO is 5 months old and will not nap in her crib for more then 20-30 mins. She still sleeps in her RnP at night (830pm-530am) because I want to wait to 6 months as per the AAP recommendations for crib sleeping at night. I started naps this week in the crib to get her used to it but she will not fall/stay asleep. If she falls asleep in my arms I can lay her in the crib but as soon as she flails her arms or drops the paci she's awake. I can't put her down drowsy b/c she WILL NOT fall alseep. She fusses for about 5 mins and then it's all out bloody murder scream fest until I go in. I calm her down, walk out and she's screaming again. I'm not sure what to do. I try to let her CIO for 5 mins but it turns into the screaming and I can't let her be like that. Do anyone have any suggestions for me? I'll be more confident transitioning her to the crib if I know she can last 45 min- hour for a nap (her normal nap time in the swing or RNP) TIA!
