Your child’s social calendar may look harmless one event at a time: a birthday party Saturday, soccer practice Tuesday, a movie with friends Friday. But add registration fees, gifts, uniforms, restaurant meals, rides, clothes and last-minute spending, and the cost of kids’ social activities can quietly become a serious household expense. Unlike rent or groceries, these costs are unpredictable, which makes them particularly difficult to budget for. Parents may also feel pressure to say yes because turning down an invitation can feel like limiting a child’s friendships. The challenge is finding a way to support a healthy social life without allowing social spending to control the family budget.
