My 2-(almost 3)-year-old has been a pretty good sleeper up until now - good bedtime routine, falling asleep by herself in bed after snuggles and stories. A while ago she suddenly refused to go to sleep without me being sat right next to her holding her hand (which can take up to half an hour) - and she SCREAMS if I try to leave her. I usually think things like this are a phase, go along with it and wait for her to go back to normal - but this has been going on for two months now! And I'm really starting to hate bedtimes, which I used to enjoy. We tried explaining gently, leaving her to cry, going back to check on her, blah, but she just screams herself hysterical. What's going on and how can I break the habit without traumatising her?!
