It is cool to see that co-sleeping is in the Bible. We co-sleep with our 5 month old.
Just wanted to point out, though, in case others haven't already thought about this... Just because it is mentioned in the Bible, doesn't mean it is a moral issue. Most likely it is simply reflecting the culture of the times. Many cultures around the world have practiced and some still practice co-sleeping (as did my husband's family who are from Korea). Let's remember that the Bible wasn't written in present day North America (where the mention of co-sleeping would be fairly impressive) but rather in a land and time far removed from ours (where co-sleeping was probably the norm).
All that being said, I love co-sleeping and it's fun to see it mentioned in the Bible.
