2 year old DD previously went off to sleep beautifully after bath, story and milk. For various reasons now seems scared for us to leave her (spent Easter in various relatives houses, routine got messed up). Now she is really hard to settle to sleep, it can take hours with tears all round. We need to get her to share with 6 month old brother at some point and wonder whether we may as well try now - would his presence in her room ease anxiety or be a disaster? He wakes still overnight but settles quickly without feeding but still has a dream feed. Any experiences?
