I am truly at a loss. My DD is 16 weeks old and bedtime has become a nightmare. She started going down very easily and STTN at about 8-9 weeks. Then around 13 weeks she started regressing. It has been almost a month of fighting to get her down and 2-4 wake ups during the night. We have had the same bedtime routine since she was 3 weeks. We've tried different bedtimes and its the same thing. I don't know what else to do. We started bedtime over 2 hours ago and my DH is currently trying to quiet her down again. Any advice is truly welcome!
