LO is over 4 months now. I nursed her to sleep for naps and nighttime. We co-sleep in that she sleeps in the pack n play next to my side of the bed, but when she awakes I'd bring her in bed with us and we'd both nurse back to sleep. I thought this worked beautifully until her sleep started regressing. She needed the nurse to fall asleep, and she'd even wake from naps and nighttime sleep prematurely. I did NOT want to do CIO, but things just kept getting worse. She will not take a paci or bottle. So, the last few days I have been checking and consoling her every 10 minutes. She fights it so hard and I feel like a horrible mother. But I do not know what else to do. Her sleep IS getting worse. She needs rest but cannot get it without me and it is causing premature wakings and her naps went form 45 minutes to now maybe 20 minutes. I don't know what to do. I feel frazzled.
