My boy has always been resistant to doing certain things. He is now 7 and getting tall and stronger. I am finding it harder to physically get him to do things he doesn't want to do. For example: he doesn't want to put pants on. I have to sort of wrestle with him sometimes(I always win..eventually). What I am worried about is when he gets older and bigger. In a couple years it will be a problem because I am a petite person with some artritis and and ever growing knee problem. I Have been managing with doctors advice and am doing O.K. now but I worry for later. Any ideas and advice for my situation?
