8mo won't sleep in cot anymore

[bumpypaws]

I hope this message will make sense, I'm not thinking straight so would appreciate some advice.
Last week DD 8m was sick at bedtime, she'd hardly eaten all day and then threw up her entire bedtime bottle. She went to sleep in her cot but then woke up a couple of hours later and wouldn't go back in. I slept with her on the spare bed that night, and she hasn't been back in her cot since. he's also not really eating still.
When we take her into her room she starts to cry, and if we try to leave her in there, even if one of us is in the room, she cries so much she retches and can't breathe.
She was always so happy sleeping in her cot, she would wake in the morning and play in there by herself, chatting away.
I feel really emotional about this, I think because she seems so unhappy unless she's with me or my DH, and she was such a happy little soul before this, whenever and wherever. She's not eaten any solids really for 4-5 days, and hardly any milk, we're just trying to keep getting water into her, although she's not keen. I don't think she's dehydrated, she's had wet nappies.
Am I making too big a deal about this? Will she go back in her cot when she's got her appetite back and feels better? Or will it get worse the longer I sleep with her? I know lots of people co-sleep anyway, but that's not for us in the long term. I think I feel more relaxed about the eating, not sure why? Maybe this is the real issue?
Sorry for the ramble, I feel like I can't see the wood for the trees.
TIA

She'll go back in her cot when she feels better. It might take a couple of days of transition, a few minutes of crying and some perseverance from you two, but there's really no such thing as a habit you can't break at this young age. The fact that she was always happy in her cot is in your favour - she's just feeling vulnerable at the moment because she's not well. Also you're coming up to the 9 month sleep regression, which is eeeeeeeeeeeeeeeeeevil.

FWIW, we went backwards and forwards with co-sleeping from 4 months to around 9/10 months, depending on how her sleep was, and never had much trouble. One day she just stopped being willing to sleep with us, and decided that our bed was Happy Fun Playtime Place, and has been in a cot ever since (now 22 months). Nothing's permanent, don't panic!

ds2 didn't want to sleep in his cot from abit older than yours. we co slept in the spare room for a few nights and he then carried on sleeping by himself in the bed. he never went back to his cot. he was ill when he came out of his cot to. he was about 1 at the time. he has side bars up

Thank you, I'm just feeling so emotional about it. tortoise, what you are saying makes sense, it's just hard to see the long term. Am sitting here crying, which is totally unreasonable, it's lack of sleep I think, I can't sleep with her without being scared of rollig on her.

Well, I used to sleep on my side facing mine, with one arm over her and the other arm crooked in front of my head, if that makes sense. That way it was impossible to roll over in that direction.

But yes, it always felt like I'd never be able to change a pattern when her sleep got bad, but really, think of how many permutations to her sleeping and her feeding you've already gone through at 8 months - i bet there's lots. This won't last. In the meantime, I hope you get a break and a nap, you poor thing!

Thank you, have just had a shower before DP went to work, and am going to meet my mum for lunch. DD loves being out and about in the buggy, and will usually sleep in the car, so that should help!
Thanks for the support!
