Sometimes kids just need space. Tricia Striano, Ph.D., psychology professor at Hunter College and founder of HowBabiesLearn.com, recommends regular outside time as a reward for work well done. “Parents might want to develop a sticker chart," she says. "Homework complete or chores complete means some hours of outside play.” The same goes for teachers; outdoor activities can happen when work is done and they should be planned and have a purpose. Unexpected outdoor time that just serves to give the grown-ups a break can make kids even antsier.
