D.W.
When my children were about this age we would turn the monitor off, but it's not like they were too far that we couldn't hear them. If we heard them cry in the middle of the night WITHOUT the monitor, we would go get them. Unsually we didn't hear their wimpers and they'd go back to sleep. I didn't put my kids in my bed with me to begin with, but once I got them for their first feeding, they usually slept with us the rest of the night. That really helped! I wasn't a huge fan of co-sleeping at first, but I got some sleep and that's what I needed. Also none of my children sleep with me today and they're 19 months, 3 and 4. So as long as you get them out before it becomes a habit, they shouldn't expect to sleep with you when rthey grow up!
