I have a daughter and the exact same problem. I do the every other night thing it is better for thier skin and their hair to be showering only every other. One thing that has worked for me is I do the warning after we are done w/ this you will be taking a shower. I also remind in the AM tonight is shower night or the night before tomorrow is shower night. I remember as a kid my younger sister used to carry on about the shower one day my mother had enough gave her the last warning and picked her up and put her in the shower clothes and all! Oh the shock......for me too! I don't remember a whole lot of problems after that because she knew what the final consequence would be. I tell my daughter that story sometimes when I am getting a really hard time.....I think she knows I might do it :)
