We have the same issue with our 2.5 year old twins. They never co-slept with us, kids of this age just like to be close to their parents so please don't blame yourself for co-sleeping initially. Getting off to a good start with breastfeeding is so important your your child's health and sleeping together in the early months gives you so much more sleep, if you hadn't done it you may have found yourself constantly exhausted and grumpy.

But I understand the issue you are in now. I really hate co-sleeping as I get no rest with a child thrashing about in the bed so invariably I end up in their bed whilst they are in mine. I have decorated their bedroom which has helped a little, and also made sure their room is very cosy and warm so they don't wake up if they are chilly. If they do happen to sleep through without climbing in with me I over the top congratulate them and make a big show of telling them how clever they are. When they come into my room in the night I gently take them back to their own room and remind them they have to sleep in their own beds. Slowly we are getting there, with more nights of undisrupted sleep. Just be patient and you will get there.

Good luck
