She was fine til she turned 3. We would read her a couple of stories and then in bed, with the light out, I would give her a cuddle and tell her another story and she would be fine. Now - the routine is the same - she is up and about, screaming for me or dp, and it goes on for 2/3 hours sometimes, with one or other of us putting her back into bed each time. she screams and screams. we have no idea what to do, and as full time working parents, are just shattered by these night time experiences. any advice gratefully received.
