@Kimmy89 I have recently just transitioned my 8 month old into his cot after months and months of co-sleeping in bed together. We are two weeks in and it's been hell. But the last two nights have been better. Not perfect, but better.
When we first moved him into his cot he would scream and cry until he was picked up. The moment I would put him down he would wake. And there were some nights where we saw every hour. For the past two nights, I have been able to put him down awake and just sing to him. No physical touch, no patting his bum or anything like that. And he's just nodded off himself. And now we are seeing longer stretches of sleep.
He still wakes at night but doesn't need too much input from me to get him to nod back off.
It's taken two weeks of consistently reassuring him and then gradually reducing my input, letting him eventually figure out how to nod off himself.
We do the same routine each night too. Bath, wind down in older brothers room, milk and sleeping bag, I put the toddler to bed then take baby into his room. We sing the same song a few times too and by this point he's rubbing his eyes and ready to be put down.
It's no means perfect and I'm definitely no expert because it's only been two nights of improvement 😂 but this is what appears to be working for us right now. Expect it to be a bit tough to begin with. I've had days where I've just cried with tiredness. It's really tough.
I hope things improve for you soon x
