hi kate
Noah still has one, there is no way he can get through the day without one... but i have heard of some 18 mo who dont...
i think the other ladies have some good ideas for you - i am certainly no expert when it comes to sleep - as you know N is still up many times in the night...
have you tried just a cuddle/rock to sleep - thats what we do. i tell him lets go in his room and have a cuddle and whatever happens, happens - he is asleep within 5 mins for his day sleep. xxx
