So our DI/DI boys are looking more alike every day, and it turns out that they have BLUE eyes. They're brightening up like crazy and are definitely turning a gorgeous baby blue, as opposed to that gray-blue. For us to have a baby with blue eyes is a 5% chance, so having fraternal twins with blue eyes would actually be a 2.5% chance, making it far more likely that they're ID. I was also looking at the bottoms of their feet yesterday, and their right feet are identical to each other, and their left feet are identical to each other, but the feet on each boy are totally mismatching. As in, Max's left foot and right foot have completely different wrinkles, but they match Miles' left and right perfectly.
This twin thing just keeps surprising. It's like the gift that keeps on giving!
