Need a new family tradition for Valentine’s Day? On each of the thirteen days leading up to the special day, mom of four Alexis Sanchez posts a heart-shaped note on her kids’ doors each night after they go to bed. By February 14, their doors are covered. 

“Usually it’s just characteristics I see in them or ways that they’re kind to others. They really love this, and I even found my eight-year-old kept all his hearts from last year in a special drawer, so that’s pretty awesome,” Sanchez says, whose other children are 10, six, and one.
