Sounds good! (Not that you needed my approval.) Be very careful with the daycare arrangements though. Most daycares are truly substandard. (It sounds like your kids are older though, so I assume they're mostly in school.)
One of us is always home when the kids get off the bus from school (it was my turn today). I don't leave for the office in the morning until the bus picks them up in the morning. So they are almost never alone. Before they were in school, we had a neighbor or family member who came over and watched them. We never had to use a daycare center. I consider myself very fortunate to have had a neighbor that we could trust to do that (and yes, we did pay her and make it worth her while).
And again, I'm not making the case that our decision is superior to just having one of us stay home and be a full-time homemaker. I'm just saying that working couples can make it work too - without being miserable.
