I wish I saw this a few years ago! However, there is one boy in this house who still likes to wear his shirt untucked on Sundays. Time to get out the sewing machine? (I'm so evil!)
My own tip - for the mothers of only boys - if you're tired of them taking things like your ear phones, pens, etc ... buy them in pink. They won't touch them. I even buy pink tooth brushes for myself to guarantee they won't use mine at the trailer.
