My kids are very used to having their photo taken. Ever since their birth, photography has been my favorite hobby. And letting them choose how to smile or stand is always up to them. Sometimes I ask for nice smiles, or try to make them laugh, but other times I just roll with it. The both have huge personalities, and letting them direct themselves is a joy.
Notice his shirt? It's one of my faves and he's worn it for three years already. I painted the map with fabric paint (which washes up beautifully) and added a little red hearts to places that have particular importance to E and I. Salt Lake City, New York City, London, Florence, Kyoto, and Tanzania. Then I listed all the places on the back of the shirt. Travel and crafts and children's clothes, all combined into one favorite shirt.
