I'm a third child, and I used to give my mom a hard time because there were fewer photos of me as a child (and no professional photos) than there were of my two older siblings. I guess it's a good thing, because I will be able to sympathize and commiserate with Susanna when she is older. I do have some professional photos of her, but not nearly as many pictures over all. It is not second nature to me to snap many pictures (and I don't have a handy dandy smart phone), so unless I am intentional, a lot of time passes between photos.
I recently made a little activity for her with plastic tokens and an old baking powder can. She has been playing with it a lot over the past couple of days. So I decided I should snap some pictures. I love watching a busy child.
