8 month old not sleeping

[KateF1107]

My 8 month old daughter has always been an ok sleeper, she's usually up once in the night for a breastfeed. However she has been swaddled and a week ago have started to transition her out of her swaddle sleep bag so she's sleeping with 1 arm out. The first 2 nights weren't great but then it got better. Last night was awful, she wouldn't settle until 1am and then was up again at 5am and tonight she's up for the 3rd time.
What's going on?
She's still in our room in a Snuzpod, I'm going to move her to a cot in her own room next week once she's out her swaddle bag. She's teething badly although no sign of a tooth yet but she's cranky, dribbling, chewing, pulling her ear so she's had calpol.
She has a good routine, it's been in place since 5 months and she goes up at 7pm with her 4 year old sister.
I just don't know what I'm doing wrong, I'm exhausted 😴
Please help!

Teething probably!

Could be anything. At 8 months old I would expect her to still be up half the night to be honest. You’ve been lucky!

@KateF1107 my DD is 8 months old too!! I think she is more disturbed in her sleep when she is learning something new during the day, she was a real monkey in the week or so up to crawling. She also gets disturbed if she has a windy tummy (I'm still trying to figure out if there is something in particular that is causing it).

Weaning had made our baby a worse sleeper - his tummy is funny. Plus teething. Plus learning new things.

Is she rolling? Could be now that she has her arm out she’s trying to practice?

There’s an 8 month sleep regression - I remember it being the worst one. I co-slept through it and it got better. I’d delay any big changes like moving to own room until it calms down. Hope you are managing to get at least some sleep.

Another vote for co sleeping through the 8 month regression. Whatever works.

I would delay it but she weighs over 20lbs and is too big for her Snuzpod now, I'm not sure I have much choice!

Are her arms warm enough, she's probably used to them being very warm if she's been swaddled for this long. I'd put both arms free though, after they can roll they need their arms for safety. She might be uncomfortable with one in one out.

You may find moving her to her room at the same time as this is too much at once. Can you bring her cot into your room even if you have to move a set of drawers or something out for a little while.
