My DD has always settled herself to sleep happily around 6.45/7pm and usually sleeps until somewhere between 6-7. She normally chats to herself for 5-10 minutes then drops off. She has a consistent routine consisting of bath around 6pm, milk at 6.20 and books and In The Night Garden until 6.50 then teeth, then bed.
In the last week, we have had several difficult bedtimes; she starts off making her chatty noises then descends into hysterical screaming. One night it took until 9pm before she eventually went to sleep, after we'd been into her several times to comfort/offer a drink/check nappy/give calpol etc. The last two nights have not been so bad, although she has cried when we've put her down and shouted/cried for 15 minutes before going to sleep.
I am confident there's nothing wrong with her; she has 16 teeth already and is showing no signs of teething, she does not have a temperature, she has been happy and busy during the day (lots of running round so definitely tired) and has a nap from anywhere between 1 hour 15 and 2 hours starting around 12.30. She will not take two naps anymore.
I'm of the school where I don't mind leaving her to cry for a short while if I know she is okay, however, I'm starting to dread putting her down as I obviously do not enjoy listening to her sounding upset and I don't know if she's going to go to sleep, or wind herself up into hysterics.
Does anyone know what could be causing these screamy bedtimes, and if there's anything I could do to go back to her old self with bedtime? We've had the odd difficult evening in the past, but nothing that has gone on for a week or more.
