Every stage with "the babies" (who are not really babies anymore) have had their challenges and have been so much fun. Sara, Martha, and I love seeing them together and listening to their little conversations. Mackenzie loves being the only girl (although I don't know if she actually knows that she is the only girl). It is so cute to watch their personalities blossom. I hate that we are so far away, but when we come home they pick right up where they left off.
