I tried at 8 months and it didn't work for us, I don't think either of us were ready. We tried again at 17 months and we cracked it!
So I had his cot in my bedroom, pushed up against my bed with the side off for a few months to get him used to being in it. Then I moved it to his room and put the side back on. We'd already established a good bedtime routine (food, play, bath, story, boob to sleep). So I followed the routine, up until boob, he had a bottle of milk and was out in his cot. I sat in the room with my hand in the cot until he fell asleep. Took us three nights to go from waking ever 40 minutes and me putting him to sleep to him putting himself to sleep and sleeping through for 12 hours.

But like vixster said, enjoy the cuddles for now. One day you'll want them to be waking through the night for cuddles :) they aren't small for long xx

I tried when she was 6m and gave up and then didn’t do it until she was 16m 😂 I wish I’d done it a lot sooner! Bedtime milk and then put her in her cot and say good night etc and she’d cry but I’d just go in every 5-10 mins until she eventually calmed down a fell asleep 🤷🏼‍♀️ maybe I’d do it slightly differently now but I definitely don’t agree with just leaving them to cry x
