Dear Grandma:
Your daughter's parenting skills could use some improvement, and yes, it's possible those kids will grow up to be overweight, undereducated crooks, but she needs to see it for herself. Your daughter knows you disapprove of the way she is raising her children, and that could be part of the problem. Frankly, the sons' recreational and food habits are not uncommon, and we wouldn't go overboard with disapproval. Stealing and poor grades are of greater concern. Stop criticizing your daughter, and when the grandchildren are in your house, set reasonable rules and enforce them. Modeling good parenting is the best you can do.
