Anyone had a spouse work for them?

My youngest son is now two and a half years old and we were able to get him a spot in our preferred daycare. My wife wants to go back to work so I asked my boss if he would hire her and he said yes (even though she has no legal experience). So my question is, what’s it like having your spouse work with/for you? My firm has 3 legal assistants already so she will be the 4th and primarily helping me. She’s very smart and more than capable, but still . . . I’m looking for some insight from those of you who have dealt with this situation before.
