DH wants to go to an out of town conference for five days (four nights) when our new baby girl will be just 2 months old. My mom will be out of town at the same time, which would leave me with virtually no support during that time. He hasn't been around newborns much and I'm trying to figure out how to explain to him how difficult it would be on me to be alone for up to five straight days/4 nights with a 2-month old, and hence help him understand why I would rather he skipped the conference this time. (note: our baby is not born yet) Any advice?
