2. What to say when your child is salivating over the latest sneakers. There’s nothing harder than saying “No” to your child’s wants. You can suggest a waiting period (see more below); you can suggest an “either/or” option (“either you get the sneakers or we go to the amusement park on Saturday”); or you can offer your child opportunities to earn the money to buy the sneakers. Spending their own funds gives kids reason enough to think twice about their purchase. 3. Don’t impulse buy—wait it out. Impulse buying is a trap for adults and children alike. So how about establishing a rule for yourself and your kids? Set a rule that you will always take 48 hours to sleep on a purchasing decision for anything over $10. You’ll see how that need subsides as time goes by.
