Son's sudden terrible sleep

[ZebraZeebra]

It's only been three nights but I'm at my wit's end!

DS is 20 months, previously slept like a dream. Last three nights he's been awake 9pm-4am and up at 6am. I am shattered and honestly? Struggling not to get really angry about it. I've shouted at him and feel terrible. It's like when you're shattered but can't sleep - he's writhing around, moaning, crying, shouting, sitting up and keeling over, then writhing around again. We co-sleep so I can't just leave him to it and I keep getting rolled on and kicked.

He's still not talking so I'm thinking it's a developmental thing but it's driving me crazy. He's fine in the day, and I've given him copious amounts of Calpol in case he was in pain but I'm not sure he is! The other thing is that I can get him off to sleep easily...but literally, he wakes five minutes later. I must have got him off to sleep 20 times last night and still, he'd wake up.

I'm dying, really struggling to cope with it and I'm pregnant. DH is self employed and really under a lot of pressure and has big things happening so I have to grin and bear it. But please, please tell me it will pass. It's insane how bad it gets so quickly :( :(

What is his diet like?

Have you tried putting him in his own room? My dd went like this at 14 months. We moved her to her own room and she woke once a night after that.

Agree with iggly. Can you tell us a bit more about his diet? Could he be too hot?

His diet is pretty good - he has allergies so we're really careful with what he has. Lots of protein, vegetables and fruit. He's been a bit off his beloved mango lately.

I'm not sure about moving to his own room - not as in we shouldn't do it just not sure if that's the problem right now. From the not wanting to lie down I wondered if I'd missed an ear infection? I could get him to sleep upright in the sling or in the slightly raised buggy and he clearly wanted to sleep but couldn't. He just kept shouting and crying and sitting up. Last night was marginally better and I doses him up with calpol.

OK could he have a touch of reflux? Is he teething? My ds had reflux and when his molars came through, my god he had quite an issue with acid. The only thing that worked was giving him a sip of peppermint tea - we would put some in his beaker of water and give him some after dinner and in the night when he woke.
I also cut down on acidic foods (even stuff like pineapple or mango!). The sitting up thing is shouting reflux to me (I.e it would be like awful heartburn to him)
