Should your child resist any change to their activity schedule, you can tell them that you may consider the activity at a later date. Reiterating that "today the answer is no," and "I am sorry, but we cannot do that today," should work well with younger children, Tayne say. For older children, and especially with teens and pre-teens, a discussion about the cost of activities should take place, Tayne says. Teens and pre-teens are learning that they have to work to buy things, and that's a good thing. Learning that you have to earn money to spend money "not only teaches them the importance of patience and waiting for the things they desire, but also the concept of money, along with fiscal responsibility and accountability," Tayne says. If you haven't already said "yes" to too many activities, it's a good idea to sit down with your child and explain to them how much money you're able to put toward lessons and camps in future, says Donna Tonrey, a marriage and family therapist at La Salle University in Philadelphia.
