your kids will. Have your partner document each month's changes to your body with a photo, taken in the same location, wearing something that shows your shape, like a unitard. You'll delight your kids, their kids, and even yourself. And it's nice to have a friend snap a few candids of you and your partner together now and then so that your children can see how much you've always loved each other  -- and them  -- before they were even born.
