Put DS (13months) in cot tired but awake, with CD of children's songs playing and leave the room completely (if I go in at all he starts to cry) He sits in bed listening to it in silence for up to 30 minutes and then lies down and goes to sleep.
Has been doing this regularly for naps, bedtime and night waking for the last week or so.
Please say it is and Ive not introduced another prop!
