Help 😭 15 month old needs rocked or BF to sleep and we are EXHAUSTED

[NattyBeaker]

If anyone has any tips I'd really appreciate it because I'm so broken and so is my husband.
15 month old is being fed to sleep for naps and nights because we've gotten back in to the habit after weeks of molars and illness. Now I can't put her down in her crib without her instantly waking and crying. Tried leaving her for 5 mins and going in to settle her but she's always standing up so don't think she'll ever lie down. Tried refusing to bf for maybe 20 minutes but it is just the only thing that definitely works. Going to get a sleep consultant but she can't come for another month.
How do you get a 15 month old to lie down themselves and go to sleep or is it a ridiculous assumption and this is just what babies do?? I can't let her cry it out and even if I could my husband always breaks first anyway

Is she not a bit small for a floor bed? She could get out if she woke up and we were asleep in the other room. She can't walk yet but she is a great climber.

If she's a great climber then she will be climbing out of her cot therefore a floor bed is safer.

Is she sleeping whilst latched on? If not is it maybe a case of split nights and she's not tired enough?

This was my experience with a much younger baby but may help. LO stopped going back to sleep after the 2am breastfeed and either wanted to play or to cry. So we swapped that for a bottle of formula, and after three nights of DP going in to give the bottle (still a nice cuddle, still warm milk)...LO stopped waking up. We had been suspicious for a while that the wake ups weren't about hunger. You could try this with expressed milk or whole milk?

My first DD was a real velcro baby, breastfed lots and co-slept with a side-cot arrangement from 7mths until 18mths when we managed to get her into a toddler bed.Tried to wean her several times off feeds between 1&2 but didn't work, as she just didn't understand.But at 2 she was old enough to easily do so, we offered water & cuddles, had a few nights of short protests and then she was fine.She got to feed in the morning/at bedtime still until she was 3, so we just said she could 'have milk in the morning' if she woke in the night asking, and she was old enough to get that.
I know it's easy, but I would honestly just try keep going through this age if you possibly can- it's the worst for separation anxiety and teething and they really need to feed quite alot sometimes.
I think trying to stop her feeding will only cause her to feel insecure and frustrated and likely make things more tricky.

@Anon501178 she is a velcro baby too. I think i need to keep going with the feeding it's so important to both of us. And it's such a godsend when she's unwell or we end up out longer than planned etc.
She slept right through last night after all my moaning! So she can do it (pray for us tonight)
