4 month sleep regression

[FruitPoppet]

My DD is 17 weeks old and we're deep in a sleep regression. I keep thinking it can't get any worse than waking every hour from 2am, and then the last couple of nights she will not be put down to sleep. Bedtime has taken 2-3 hours with her up and down consistently, and when she wakes in the might she's thrashing about and tearful, and then will only sleep in my arms and will not sleep on her own once awake. She can be asleep in my arms for an hour, and the second she touches the crib she is awake and crying.

I've tried cosleeping and it's just not enough, she wants to be cradled in my arms, or she's awake and crying.

I'm just at such a loss at how to help her. Im trying to help her soothe in the crib but it just always ends up the same with me getting her into my arms and having to let her sleep before tentatively putting her down in the hope she may do another hour without me, before doing the whole cycle again.

Very exhausted and have no idea how to get through this bit.

you say she’s liking being held . Have you tried the sleep sacks or the breastfeeding pillows ? Obviously don’t let sleep on breastfeeding pillow all night but once you’ve re settled her back into cot with the pillow take the pillow away after half hour or so so she’s in a deep enough sleep

@justmeandtheclanits a good idea in theory, but would still leave me up half the night extracting a pillow from underneath her half an hour after she goes down (pending it works and she doesn't wake the second it's removed) and she's currently waking every hour...
