Mrs Casey just got her birth certificate with one minor change. She wanted to change her middle name from Ann to May. At first I hesitated because both my ex's had the initials LMS and I didn't want that constant reminder of them.
But then I decided that I would be so focused on being a good dad, I really didn't care what her middle name would be, she would still be my little girl no matter what she was called.
It also turns out that the family isn't calling her by her Chinese name any more, everybody is calling her Lexi.
