Does anyone here co-sleep? What does co-sleeping look like for you? How old are your kids and which ones co-sleep with you?

When I was away on a work trip, my husband started letting our daughter fall asleep in our bed and then let her sleep there all night. I've been slowly weaning her off of this (my God, this is so, so hard) but she still comes into our bed around 2am every morning. Goodbye thoughts of morning nookie....Sigh.
