My dd (8) is quite a mother hen to my ds (almost 7). I appreciate how she'll pour his milk for him, go get things for him, etc. . .my problem is, he takes advantage of it. Last school year, I had to keep reminding dd to let HIM do his own homework. It's to the point now, if I ask him to do something, he pitches a fit. I have tried asking him to reciprocate Sissy's kindess, kinda' tit-for-tat, but he won't. I don't want him thinking he can go thru life expecting ppl to take care of him like this. Nor do I want dd being taken advantage of by Bubby or anyone else. Any suggestions?
