Dd is 21 months she still feeds to sleep most of the time (for daytime nap and bedtime).
She started asking for 'cot' lately after feeding, so I lay her down and she asks me to 'rub' her back. Sometimes she drifts off, sometimes she doesn't! Don't see it as a problem to be honest as I'm here all the time, however I'm due number 2 in August so I'm a bit anxious about that!
She still feeds in the night too, but that's a whole other thread!
