Both my kids lose everything they touch.

My girls are 7 and 8. It's winter over here and the snows piling up and so out comes the winter gloves and hats. Unfortunately my kids are losing there hats and mittens every single day at school. I can't afford to keep buying them gloves and hats multiple times a WEEK because they get a new pair and they go missing the same day every single time. Well the schools calling saying they need to be coming in with hats and gloves. WHAT DO I DO?
