So, I just thought this was interesting...these are pictures of both of my girls when they were about three to four months old...can you tell them apart? It is interesting because the thing I hear quite often is that they don't look alike. People always see Reagan and say she doesn't look anything like Mariah. But, then you see these pictures and it is hard even for me to tell them apart. But, just to answer the question, the top one is Reagan, and the bottom one is Mariah. Aren't they adorable?
