Yeah, you bet she’s a girl. There are several ways this became apparent to me.
First and foremost the doctor told us she was a girl. Always good to get a professional opinion.
Second: She yells. A lot.
Third: There are times when nothing seems to make her happy.
Fourth: She survived against impossible odds. The stats show that girls have a higher survivability rate, when born early, than the boys do.
Fifth: I’ve changed her diaper more times than I can count, and besides the obvious anatomy differences, the technique is different. OK first of all, the fact that there has to be technique changing her diaper means it’s already tougher than changing a boys diaper. With Frank, as long as I didn’t crush his grapes in the process of a diaper change, it was all good. With Anne Mare I have to be more technically proficient. I was schooled on this when she was a few days old and not yet two pounds. At first I thought it was a preemie thing, but then was alerted to the idea that it would be this complicated all the way through to potty training.
Sixth: She likes to supervise jobs she would not do herself.
Behold, her close inspection of my kitchen cleaning skills.

Little more elbow grease, junior.
But given all that, the notion that there was another girl in the house finally set in one day when I noticed this.

8th wonder of the world
And this…

The habitat of the indigenous creature known as Girlous Alotaclothesus.
What you are seeing in these two photos is a phenomenon that occurs once or twice in a millennia. Well actually in this house it occurs at least twice a month. But, you are seeing visual evidence of the presence of girl, in her natural habitat. The first photo, taken at great personal risk and safety, shows a completely full to over flowing hamper, while the second photo simultaneously shows her closet full of clothes.
At first I thought it some kind of witchcraft, voodoo, or black magic, based loosely on the principal behind microwave cooking. But as I continued my study, I found this is a natural occurrence around the very small female of the species. I don’t have enough data to draw conclusions on the entirety of the species based on age.
Yet.
The study continues….
