My guys go home quite dirty most days in the summer. It's to be expected during our short lived summer. I've not had any parents complain. I will only change them if really wet or head to toe filth. Usually a wash of exposed skin is enough. My clients often forget to leave extra clothes as well, so a change if often out of the picture. If I know a child has somewhere to go after daycare, I'll make sure they're washed and changed. Otherwise, it's just the end result of a great day together
