After nearly 2 years of very hit and miss sleeping with my DTs (2.3) they finally started sleeping well around the New Year... 7.30 - 7ish each night with around a 2 hour nap after lunch. In the last couple of weeks, DT2 has become quite hard to settle at both naptime and bedtime, with me/OH having to go back in a few times sometimes to settle her down and she's also waking several times a night, absolutely screaming the house down.
If she was just whimpering a bit, I'd leave her to settle herself back down, which has never been a problem in the past, but from the screaming it does seem as if she's having nightmares so needs some cuddles and reassurance. I've tried putting a night light in their room, but it hasn't helped - I think the shadows from it scared her even more; I do sometimes leave a light on on the landing after she's woken up. She does normally stop crying the minute I go in and is usually happy to go back down, when I say I'm going back to bed and it's time for her to get back in her cot.
She started pre-school this term (with her DT and it's the same one DD1 goes to) and settled in really well. She was slightly more uncertain when they went back after half term, but the teachers say that once I've left she has a great time and joins in fine, so I don't think that is unsettling her. I've wondered if perhaps she's ready to give up her daytime nap and so isn't tired enough at bedtime. But other than that I'm fresh out of ideas as to how to solve this problem. I'm still getting way more sleep than I was a year ago, when both of them were waking several times a night, but you get out of the habit of sleep deprivation, and this is really taking its toll on me!
Any help/ideas gratefully received.
