Now that someone mentioned surnames, I remember being asked (I was about five at the time) which surname I preferred. I opted for my father's because my mother's was used for a stupid nickname in kindergarten. (Too young to have feminist consciousness at the time - I didn't even know that it was tradition to default to the man's name.)
This is very important whenever you make a choice that happens to be something women have been forced to do as default: Make clear that it is a choice, and that you could just as well have chosen something else.
And as some people seem confused about this, I will repeat it: Making a toddler grow her hair so long that it requires extra care, like brushing or braiding, is a terrible, selfish thing to do. I wasn't even aware of what I looked like at kindergarten age, and I will be forever grateful to my parents for enabling me to be HAPPY, and not requiring me to be DECORATION.
Long hair doesn't only require extra care, it also gets in the way a lot, limiting the child's activities, or even endangering the child. Why do all that to a tiny person who doesn't care at all what she looks like?
