you don't have to tell the kids to do something right. You do the rights things and your kids will see and follow you
Day before yesterday, I was listening a talk show.
Lady asked dentist that her 3 year old kids are very resistive to brushing, she has tried to convince them through talking but no avail. How can she motivate them.
Dentist replied, do brushing in front of the kids. They will see her, copy her, and kids will not treat brushing as a tedious task.
