My seven year old daughter has been bathing by herself for some time now, but I find I have to send her back in for another "rinse" quite frequently as I can still see suds and bubbles in her hair from her shampoo. I think the problem is two-fold in that:
She is using too much soap despite didactic suggestion about how to "measure out" the right amount.
She simply doesn't rinse well enough. On this count, the background knowledge that she has been fearful of getting water in her face since she was a baby/toddler and that while she has mostly moved past this fear, I think she may still be a bit trepidatious about it, is probably important.
How do I make sure she gets all the soap out while still honoring her privacy and without having to have her come to me and get "checked" before she can get dressed all the time?
