When my DS11 was a baby, he was mistaken for a girl every day. It didn't matter if he was wearing a blue t-shirt with a pick up truck on it, it still happened. I couldn't have cared less when someone told me what a beautiful little girl he was, half the time I didn't even bother to correct them. They are strangers, what do I care?
Sorry, I think the headbands and pink bows stuck onto girl babies' heads are silly, too.
