My twin nieces turned four years old this week. I remember the day they were born and how tiny they once were (the above shot is from their baptism when they were two months old).
Not so tiny anymore. They're growing up so fast (didn't adults always tell you that when you were little? I'm such a boring grown-up now!) and will soon surpass their aunt in height, which isn't exactly saying much. Happy Birthday, Alex and Stephanie!
