It was not something that was intended, it was something that seemed and felt right after he slept in our bed after a long no-sleep night. Without either one of us fully waking we were able to nurse and then doze back off. I didn't get up all through out the night to do a breathing check.
Some people worry about rolling over and smothering the child.
Truth be known, the same instinct that tells you not to roll off the bed is the same instinct that tells you where the baby is. I slept in the middle with Kristofer next to the bedrail. Since he has gotten older, he likes being in the middle though. Of course there are times when it drives me crazy, my husband snores and our son likes to sleep horizontal. Research has shown children who sleep in a Family Bed are more content, feel safer and more secure, sleep better and longer and are often more loving with their parents and others.
