My 18mo girl usually sleeps from 7.30ish til 6 without waking, in her own room. About a week ago she started waking and I have been sleeping in her room - she stays in her cot and goes back to sleep fairly quickly. I've been away for 4 days and the disruption seems to have affected her - on 1st night she screamed for 2 hours until DH took her into his bed. She woke up between 12 and 4 and played as if it was the middle of the day. Less bad on days 2 and 3 but she still had to sleep in his bed. Now I'm back and have just tried putting her to bed as normal, and she is screaming herself hoarse. Any suggestions about how I should reestablish her routine? NB - she has not had this kind of reaction before, when I went back to work, or stopped work, or moved from our house to a small flat in Paris a month ago. All advice welcome! Thanks in advance.
