My baby girl is week 16. She is able to smooth herself to sleep after the feed at 7pm for the past 1 month. However, since 8 days ago, she has gone back to her old sleeping habits from when she was 2 months. She starts to cry when I put her down to sleep. When I pick her up, she stops crying. She can scream for 2 hours. There are no changes in daily routine or environment. I wonder what has happened to her?
