On last night's Hoarders, 7-year-old Alex was unable to part with anything, from toy packaging to used cotton balls. As a child whose Barbie shoes were—without exception—casualties of a merciless vacuum, it's hard not to empathize with him.
When my kid was little, she also wanted to save every little thing. We used to joke that our decorator was Fischer-Price.
Solution? Dad took her out for the morning, Mommy bagged up anything I thought she wouldn't miss. The bags stayed in the attic for a month or two, but if she asked for something specific, it was retrieved. Otherwise, after the waiting period, it was HELLO, Salvation Army!
I will offer up the hint to used dark, dark bags.
