Ds is 20 months, and has coslept exclusively since he was about 5 months old. He typically wakes every hour until I come to bed, and then every 2-3 hours, nurses briefly (or walks with dh) and goes back to sleep. The problem is that he has become a really bad bedmate lately - kicking, rolling over on my head, turning sideways so I have no room in our king bed, kicking all the covers off, wanting to play with my breasts, and waking more often. So we decided to try to transition him to his own bed in our room. We took the crib mattress out of the unused crib and set it up on the floor a few nights ago. The first day he took his nap there, but it was shorter. Then he nursed to sleep there, slept for 2 hours, and then we took him into bed with us when he woke. But since then he will nap there, and will fall asleep there, but will not stay asleep. So eventually we take him into our bed after an hour or two of trying to get him to stay asleep. He's not crying, just not staying asleep. He will get up and walk out if I don't nurse him or dh doesn't walk him. But it's not working anymore.
So my question is: How did you transition? Did you just stick it out straight through with no sleep until they slept there? Did you take them back into your bed for awhile and then try again later? Did you start them there and then let them come to your bed if they wouldn't stay asleep?
Any stories, suggestions, words of advice would be appreciated!
