Utopian I decided I wanted DS to sleep in the cot about 2 weeks ago. So I fed to sleep and put him down in it. He obviously woke up being put down, so I picked him straight up and cuddled him. Repeated that for about 30 minutes, not feeding just cuddling in a dark room. He went down in his cot when he was sleepy enough to.
I've done the same every nap since, and when I put him down at night before I go to bed. It takes about 5 minutes for him to go to sleep now (on a good day, 15-20 on a bad day), without milk. After the first week DH started tryingr, and can now put him down to sleep too.
There was no crying really, and tbh it's not "self settling" but both DH and I can put him down for naps and bed, and I feed him when he wakes up after a day time nap, or after 4 hours/when I go to bed at night.
I thought it was important for DH to be able to settle him, and for him to be able to sleep without needing fed to sleep. However I still feed him to sleep at night, or if I feel like it during the day (or if I feel he needs the comfort) and I love doing that.
I was going to say though, since putting him down in his cot he'll now sometimes go down with his eyes open, grab his teddy dog and slowly close his eyes to sleep. No patting or anything required. I think that's maybe the start of him learning to self settle, maybe.
