DS was 2 a couple of months ago. He wasn’t the best sleeper as a baby but for the last 6 or 8 months he’s been pretty good, going to bed ok and getting himself back to sleep if he wakes in the night. We went on holiday a few weeks ago and tried to keep to his routine as much as possible but he went to bed later than normal, he seemed to deal with it ok though. However, since the day we got back his sleep has been terrible, waking numerous times a night and screaming until we go in and lie with him. I’ve read there can be a 2 yr sleep regression and I think he also has a tooth coming through. Can anyone reassure me (please!) that it’s just a phase and that I haven’t completely ruined his good sleep habits by going on holiday? I don’t remember DD going through a regression at 2 years, at least not like this.
