My oldest is going two days a week. It's so nice to only have to worry about one. When she takes a nap though I usually take one too (If I've been on baby duty the night before).I'm the latter (used to be the former), but now that school is in session, I've got the kids in part-time preschool 3 days a week. It's great to drop them off at school and hit the bookstore to write for an hour
I don't think finding the, or at least enough, time to write is easy for most of us.
