Re: What if he's still nursing?
Do you ever leave your LO alone with DH? If not, you might try leaving him with DH for a few hours at a time, a few times before the trip and see how your son does. If your DS is used to being with you all or most of the time and then you just leave him for a weekend (still nursing or not), he may have a difficult time. I know we all need our breaks as moms, but I think it's important to make sure that your DS is ready for such a long separation first. He'll grow quickly and you can always put together a weekend like this when he's a little older.
