Five month old fighting sleep

[Mamaofgirls]

Please help me my five month old has always been a terrible sleeper but the last two weeks it has gotten worse and worse.
She is ebf and refuses a bottle. She goes to bed at 7.30 and then is awake every two hours if not mostly every hour. This would be fine except during her sleep she is kicking flapping her hands around. We cosleep and she is swaddled and it’s not hunger in those periods always. I don’t know what to do I’m exhausted she is miserable as obviously overtired. Any suggestions great fully received!
I should add she has reflux and is on medication for this.

Sounds awful. Is she too hot maybe? Or maybe it's time to get rid of the swaddle? Sorry I can't be of much use but hopefully this will bump it up for someone with more knowledge

There is the infamous four month sleep regression. Could be this. It's a permanent change in their sleep cycles which can cause regular wakings until they get used to it. We had it bad too. I hope things improve for you soon.
