My dd wakes most nights at about 3am and winges for a while, normally I bung in her dummy and she goes back to sleep. She then wakes at 4ish-5, at that point I give her a bottle and she sleeps until 8ish. I can handle this, but the problem is she will only fall asleep being held and rocked. Durng the day she is a nightmare only sleeps being held or in the sling. Have heard about cc but is she too young at 3 months?
