When I was growing up, I learned to do all the housework.. and got plenty of practice!
My children have all had chores. I have found that the less chores they had, the lazier they were!
I think that chores are an important way for children to learn and practice all the things they will need to be able to do as adults. Doing them as they grow up gives them time to ask questions and make mistakes while there is someone right there to help. Aside from that, I feel it is an important way that they can contribute to the family.
Mind you, I wish I could say that they joyfully bounce out of their seats and get to their chores while smiling and whistling a happy tune, but alas, the opposite is true! There are times when I believe it would be less painful to do it myself, but what would they learn from that. So, I suffer through their whining, and I cajole them into getting their chores done by any means necessary!
The rule at the end of the day is: You can feel however you want about having chores to do. Your feelings are valid. You can tell me how you feel.. once. You still need to get your chores done.
