Both Grace and Claire slept in our bed with us most nights for the first few months of their lives. It's a personal decision, but both Michael and I felt like it was safe to do this (and it made it possible for me to stay sane during the endless nights of feeding). For the record, both of my girls are incredibly easy to put to sleep in their own beds now. We're glad that those months of co-sleeping haven't created a situation where they need us to be with them as they fall asleep or during the night.
I still think though that for our next baby I'd like to get one of these great bed attachments, called a Culla Belly. Check it out. It's winning all sorts of awards.
