(This is you "smiling" in your new big girl bed)
Little girl, I love you. You are so darling to me. I was expecting a little brother for you. I don't know why, I just thought this little one would be a boy. But, based on how much I love you and how much fun you are, I can't imagine that I will be anything but thrilled when my next little girl makes her appearance. I just want you to know, though, my Haven, that you are so special to me. The whole reason for having another baby is not to replace the one we have, but because you are so great it would be a shame not to repeat the process. Your parents love you and I hope we do a good job of continuing to make you feel like you hung the moon. Even when a new, very special one comes along. We'll think she hung the moon too. We'll think you hung it together.
You are the very best thing that's ever happened to us. Your daddy and I both agree. We want more of the same (but different) this next time around because you give us so much joy.
