No, we haven't been away (*I* haven't been apart) from our 8month DS (we do travel without my husband sometimes). We still nurse and cosleep. But once he's night weaned (whenever that will be!), I would love LOVE at least an over night with just my husband.
I'm super lucky that my inlaws live within walking distance and they have a super excellent rapport with DS. I'm beyond comfortable with the idea of leaving our sweet boy with them, and I know they look forward to overnights. (But in practice I'll probably think of DS the whole time!)
