you can get these things that they hold on their forheads taht stops the water from going on face and in eyes, maybe try that
We have one of those and it works well but the girls still scream their heads off and want to get out of the bath quick smart so I have been trying to wash their hair while I'm in there too and they can lie on me but that doesn't work either. I gave them a washer to hold over thier face and that works sometimes but they are always upset. They aren't too bad if I wash it in the shower but we have so much drama and we only do it once a week
