We got really lucky with this double daddy windfall too. The boys step up to the plate on all sorts of tasks big and small, even though they aren't obliged to share the many burdens of full-time parenthood. They've become masters of arts and crafts, makers of oatmeal, singers of monotonous child songs. They don't even mind the endless cupcake making and homework doing. The occasional family photo refuels their patience.

Meanwhile, she thinks they hang the moon. When they bought a country home last year, they designated a room for her with a comfy twin bed and a lazy stuffed bunny in an antique rocking chair. She was all over it.

Last weekend we visited and she spent a full day dragging them around by the hand -- to do the gardening, barbecue burgers, paint ceramics and shop. She rode a bike all by herself for the first time as everyone cheered her on. This kid will never complain of not getting enough attention with four camera phones pointed at her to send a record of her every accomplishment off into the world of grandparents and Facebook and Instagram.

Not every gay family would have things this way. Some women we know preferred anonymous donors because they wanted clarity all around. Some men prefer to have only children that are exclusively their own. We like our choice. We are undeniably Luna's parents, but there is a special place for the daddies, forged by our trust and enriched by her love.

She knows where she came from and that the daddies made it happen. And so do we.
