Baby won't be put down in next to me cot

[SMLSML]

My baby just turned 6 months old and all of a sudden will not stay in her cot in our room at night. She's always been a contact napper but would be put down at 10pm and sleep til 7am. The last three nights she's woken at 2am and won't settle unless she's on my husband or I. We've sat in her rocking chair for over an hour each, she goes off to sleep and then won't be put down even in deep sleep her eyes ping open straight away. We've had to cosleep otherwise we wouldn't have slept at all, but I really don't want to do this, my back is shot as it is so can't continue. Wonder if anyone has any words of advice or reassurance if you've been there. My first went through this but not as bad 🤣 feel like we've tried everything from keeping the heating on, more layers etc. Only thing left to try is moving her into her own room in case she's hearing us and keeping her awake maybe... Any advice welcome!

Maybe teething or sleep regression. Mine used to sleep in the next to me so well, now we’re eight months and only sleeping in the bed literally next to me, but working on going back into the cot.(still in same room) To be honest every time I think we’ve cracked sleep, he has another few weeks of loads of wake ups! Just going to go with the flow as it seems it constantly changes. Is the mattress comfortable? The next to me ones are quite hard so we have a topper! Maybe try a hot water bottle warming the space where you’re going to put her down so it doesn’t feel a huge change of temperature?

It's just a phase, it'll get better. I found that babies' sleep patterns change frequently in the first year. Personally I would try moving her into a cot in her own room - she's 6 months old now so she doesn't need to be in the same room as you any more. She might fight it at first, but she will get used to it and you'll all sleep much better for it. This goes for naps too.

Consistency is your friend really. If you're going to keep baby in the cot then you have to stick to that and don't cave in. Otherwise I feel like they become more irate because they've learnt you will give in eventually, once theyve done a certain amount of fussing first.

What about if you just put your hand on her chest so she knows you are there, without picking her up?
