Leaving baby home alone with daddy for the first time?

I have a wonderful husband who is already madly in love with his unborn daughter. I have no concerns in that area. But just that little bit of "I've carried her for nine months and nobody can take care of her like I can."

I was talking to my SIL today because she's taking her 7 week old son to daycare for the first time tomorrow as she goes back to work when I realized I'm probably going to be nervous even leaving her with dad.

And I know in my head everything will be fine and he will do a great job. But just that first time leaving her with ANYONE other than me... I think I'm going to worry. Anyone experience that with their first?
