That's one of those "what the heck do i do now" type times...i remember how strange it was nearly 3 years ago when i put my first baby in our car seat and drove home with the new addition...it was very strange! The second was a little less shocking, but he made up for the lack of shock value in the middle of the night just the same.
I'm sure you're a great dad, Andy! Enjoy while they're still small!
