My DS is 9 weeks and about two weeks ago started to self settle. He sleeps on his tummy and is bf - although he gets a ff top up for his dream feed.
We were rocking & feeding to sleep up until a couple of weeks ago - my back was in agony and I was in ribbons. A weekend at my mum's saw me leaving with him self settling. She made me leave him shouting after he'd been fed, burped, pooed etc (note: very diff to crying IMO) and he dropped off in about 10 mins? Key for me has been to catch him when he's tired & not over tired. And not feeding him to sleep when possible. It sometimes happens for night feed, but I try not to make a habit of it. Leaving him that first time gave me the confidence to try it more at home and now two weeks on it's going well.
I'm not saying he manages it every time. But 8/10 sleeps he's able to get himself off. For naps I watch for the yawns, then take him to bedroom, give him a cuddle and sing same song (poor kid!). When he starts to yawn some more, rub eyes, get heavy etc, I put him down.
If after ten mins he's getting upset vs. shouting/grumbling, I'll go and give him a shush pat. And then pick up and cuddle if he still isn't going off.
Although some think it's b*llocks about sleep cues, I really think my LO has responded to it. Bath at night etc. And sometimes when we're out it's all a bit skew-wiff, but I'm now starting to see a pattern emerge with his naps.
I'm realistic and don't expect it to last...but I am feeling happy that we've managed to crack it once. So hopefully when he starts to be a monkey at the 16 week mark I'll be poised and ready to try and get him sorted.
