I have two sleep problems in one baby. The first can't be helped, as it's medical and we just have to wait it out (not what I wanted to hear from the docs!), but it's kind of tied into the second.
Basically, my youngest has a tummy problem, which means at night she gets really really gassy and bloated, but she struggles to release the gas. Thankfully she's getting better at this, so I have to go to her less often in the nights, but she does need to be quite free to move around, otherwise the gas pains wake her.
Problem two is that with the necessary moving to relieve pressure in her tummy, she's crashing into the ends of her cot, and now that is causing her to wake.
In terms of solving her gassiness, there's not much I can do (we do bedtime massage, but doctors say no other treatments are advised). For her crashing about, I want to be able to tuck her firmly in place with a blanket, but that would then stop her moving, so the gas pains would wake her...
She doesn't lose her limbs to the outside world, so I'm not sure it's the weavey bumpers I need, as she'll still hit the sides, even though they'd be a little more padded... She really does throw herself around with force - I hear the crash from her room before anything comes through the monitor!
For info, she's 1yr old, so we've got a while left in a cot, and she sleeps in sleeping bags, which allow her to move as she needs to, but slightly slow her down, so it takes longer for her to wriggle to the far end and headbutt it.
So, please tell me you have a brilliant solution! I'm up about seven times a night, either comforting a child with a bumped head or helping her pass wind..! She and I both need a solution!
