Congratulations, brother. I'm in favor of little girls. You already got other kids and so don't need it, but I'll offer advice anyhow: hold her every chance you get. I remember the day I realized my first girl was too big to easily carry around the house, and I thought of all the times I'd screwed around with this or that when I could have been holding her, and now that time was past... I cried. My youngest is the beneficiary of that realization; she gets a pick-up whenever she want it.
Here's my first daughter, doing a little post-season scouting.
