I just read in another thread where a woman washes her childs hair 3 times a week and wrote that people think that's gross. (btw, I don't think that's gross 3 times a week)

I only wash my childrens hair (nearly 6 and under) twice a week. Once after swimming lessons on a Tuesday and then on a Friday night after the school week has finished.

Do you find this gross and what do you do??
