Order of photos: 1. Sonia 2. Nadia 3. Nadia 4. Sonia. Despite the obvious differences, color of eyes and the amount of hair, Sonia and Nadia still show a strong resemblance to each other. Nadia at 2 months was 23 inches in height and 10 pounds in weight whereas Sonia is 23 1/4 inches and 11 pounds 5 ounces. I should explain the last photo of Sonia. Nadia apparently wanted Sonia to play ball and stuck those there while she was sleeping, I often find baby dolls and all kinds of toys lying with Sonia whenever I turn my back. Fortunately, Sonia never seems to mind.
