WARNING: This commercial is likely to induce tears.
I have written my daughter at least once every two months since setting up her account and have included pictures, videos and shared stories of what's going on in our lives at the time I'm writing. As the commercial states, I can't wait to share this with her when she's older some day! I figure there will be tons of things I forget as time passes and this is our own little time capsule gift to her. One day after her father and I are long gone, she will then have these to share with her kids and grand-kids as well.
In a world where we are now given this kind of opportunity with such ease and little time, why not? You're giving your kids the best gift you can -- a life full of loving memories!
