My 9 week old DD WILL NOT go down to sleep for the night until at least 10.30pm. The last few nights it's been after 11. She will sleep in my arms, but the minute i put her down, either in her moses or her bouncy chair, she snaps awake and sobs. Can't settle herself at all. Falls asleep on her last feed and then wakes at about 4.30am, for a bottle, then sleeps til 7 ish. So, when she does go to sleep, she sleeps well, and only wakes once, but it's getting her down that is the problem. She has no pattern or routine at all in the day, but has bad colic and screams much of the day and ALL of early evening. DH and i exhausted as is 3 yr old DS. help!!
