Hi, I also have two girls that are 4 and 6, and I also got tired of the bath. Leaning over and the crying and especially the water all over the floor. That was just an added chore. So we switched to showers and that works out pretty good. One gets in and wets herself, usally the six yr old first. then my 4 yr old goes in and while she wets herself, I'm washing the others hair while she cleans her own body and sometimes I do need to remind her where to clean, under arms, neck, etc. So when she is done, I have her rinse off and start on the other child, same thing. when she is done and rinses off, I'm checking to make sure all the shampoo is off the other one. I usually do this first thing, then they can play for a bit after. That way when they are ready to get out, or it's time, then we don't have to wait and say that we still need to wash. The older one likes to get out faster than the younger one. So she gets out and she starts to dry herself, I'll help if it looks like she needs it, but she is getting old enough to do it on her own. When she is ready, I then take the younger one out. One thing, when they do play, watch that they don't stand on the edges of the bath, I've caught mine doing that. Also, they sometimes like to take a "showath" Have the shower going and plug the bath, keep the curtains/door closed.
