DD2 only stopped feeding or rocking to sleep this year! And she did it herself!
Gradually over the last month or so she would want to lie down on her own, so we would put her down on her flip out sofa. Then she would bring her blanket to me and want a cuddle/feed to sleep.
Then I thought - maybe its time to get her to sleep in her room instead of the loungeroom, so I took her upstairs and cuddled her till she indicated she wanted to lie in her cot.

It took a good 15-20 mins the first night, of her rolling around, wanting to be picked up - but then she just wanted to lie down again. Eventually she went to sleep, and it has been easier every night since.
In my experience with both my girls they just naturally grow out of being fed/rocked to sleep. Both of them have done it around 14/15mths!

I will keep gently putting her to sleep in her cot, until I can put her down awake and leave the room. With DD1 I did it gradually over about a month. But really, I will do whatever works
Not sure if that helped at all!
