She used to be a great sleeper, sleeping through the night from about 14 weeks and not wanting a night feed. She still sleeps solidly for the full nine hours sometimes now at 8 months. But for weeks and weeks, I haven't been able to get her to sleep longer than 9 hours at night and 2.5 hours during the day. No matter what I do, I can't get her to sleep past 4.30 am. She lies wide awake in the cot for hours, either shouting or crying, and nothing makes her back to sleep.
I've tried everything: more awake time, less awake time, later bedtimes, earlier bedtimes, three naps a day then two naps and then back to three naps, tiring her out, fresh air, feeding her to sleep even though she doesn't need it or really want it..everything. It's been too long now to be a regression, surely? I don't know what to do. The 4/5 am starts are killing me. I work in a school, and I am shattered every day. It's all so exhausting.
Does anyone have any tips? I'm worried for her because nine hours doesn't seem enough for her, and also it's not enough for me. If I put her to bed later then she's still up at 4.30 so she gets even less than 9 hours and doesn't make up for it during the day.
Am I being unreasonable to think I can diagnose the problem or to search for a solution?
