For those who co sleep/ no about co-sleeping?

I co-slept with all my children - 12, 9, 8 months. My littlest one is still in the bed with us. I can sense every little movement he makes, my husband however doesn't, so I sleep in the middle. Lot's easier to feed that way in the middle of the night! After they wean, I start the move to their own bed, by going in crib right next to mommy, to toddle bed beside our bed, then move it across room, then eventually to their own room. 12 year old did fine with that, still sometimes find 9 year old on couch in the morning!
