She's 18 months old and was a terrible sleeper (up every 45 mins or so with the odd 2 hour stretch) until about 6 months.
Now on a good night she sleeps ok - goes to sleep on her own in cot with me in room and then wakes every 2-3 hours for a quick feed and straight back to sleep. That works for us and it had improved to every 4-5 hours on a really good night. I think this is pretty normal.
But we have regular periods where she will go to sleep ok and then after the first wake, feed as usual and go to sleep but within five minutes start tossing and turning and sometimes even throwing herself about (with her eyes closed and making sleepy noises). She'll do this for 20 minutes or so until she is eventually so frustrated she starts crying (if I haven't intervened first).
It's like something is really bothering her physically (when she is ill she is just like this) - sometimes I can put it down to teething but I'm not certain it's always that. I've checked her for worms or any itchiness, tried different sleeping bags/temperatures and she has an air purifier. We bedshare occasionally but it's more for my benefit as easier than getting up a lot, but it doesn't really help her that much as she does the same thing. Sometimes she coughs a bit, so reflux has crossed my mind, but she has never been refluxy even as a baby (I know silent reflux exists). She eats and drinks well in the day and I think her diet is as healthy as possible for a part time veg dodger. She isn't constipated and does a normal looking poo once or twice a day.
I've asked health visitor and paed and they have talked about sleep training. I'm open minded to a gentle form when I'm confident she is well and already sleeping ok, but I'm convinced it's the wrong thing to do when she seems uncomfortable and struggling.
She was born with two congenital birth defects which she'll need surgery for in the next few years. They are rare but she is seen by specialists who have told us they don't cause any pain. Sometimes though I do wonder if this is bothering her which breaks my heart and also makes me feel sleep training isn't appropriate.
On the other hand, I'd like her to sleep better for her development needs - last night she was tossing and turning and waking hourly to two hourly again. This will usually go on for a few days before she's back to normal. I've also checked her amount of day and night sleep and I think it's right and she's not over or under tired.
It's so hard to know what the best thing is! I could also night wean (breastfed) but I think all it will achieve is removing a sleep tool that helps us because I'm sure she isn't waking for a feed as such.
Help!
