I love co-sleeping and would still do it - if only little wiggle-bottom didn't push the two of us out of bed and sleep worse. We co-slept until DS was 10m old, he wanted his own bed by then and refused to sleep with me.

He has to be SUPER scared or SUPER ill to co-sleep now. Even then he doesn't really want to go to sleep but he will, given time. (And we only do it because I'm tired and cold and DH won't get out of bed so blow it I'll get into DS's, like last night.) He is so much happier when he wakes up after co-sleeping.

Get your DH to get up to fetch the baby each time he wakes. That works well. My DH slept on a camp-bed in another room for a while when he "needed" sleep (I didn't, apparently). Not ideal but it does work.
