My LO just will not fall asleep at night. It seems to be getting worse every day. It is now taking up to 6 hours to put her to sleep at night. She doesn't fall asleep nursing anymore so I have to rock her a very specific way for longer and longer and longer. Then when she falls asleep I have to hold her for a while before putting her down. 10 minutes after I put her down, she wakes up and we have to start the whole process again. Puttng her in the crib drowsy but awake does not work at all as she instantly opens her eyes extra wide and starts fussing. Pedi says that I have to let her cry because she is a big girl (12lbs) but everything I have read says not to do that yet. I don't know what to do anymore, help!
