Background: A few months ago we had a well-sleeping kid, zero or one short wake up a night and pretty much 7 pm - 7 am, life wasn't too bad. He slept in his own bed in his own room with a blanket and bunny.
Disruption: Some temporary accommodation including a temporary cot we needed to use for several weeks. He slept fairly well there, maybe not quite as well as home but nothing concerning. Now we've moved back though things are very different. He's waking several times a night, often needing an hour or even two more to put back to sleep.
Problem: The most common pattern is he wakes, I quietly and as boringly as possible lead him back to bed, he lies down, grabs bunny and I put the blanket over him. He appears to go to sleep easily and his breathing slows. I leave and 5 mins later he's up again. This can last 2.5 hours on a bad night. Some other times he's harder to get back to sleep and I struggle to ever leave the room. It's been six weeks and I'm struggling.
What I've tried: He's warm enough, fed enough, drinking enough (and often drinks water on wake up), breathing well, he's not particularly sick or teething, changing his nappy sometimes helps but it doesn't need changing. I've tried with and without white noise and with and without a small amount of light. I've tried shortening his daytime nap but it hasn't helped and I think he's now generally a bit short of sleep and cranky because of it. He has got pretty clingy over the time and he does want hugs/contact overnight so maybe something there?
What should I try next? What has worked for you?
