Congratulations! She's beautiful! Welcome to parenthood.
Does her name work in both Chinese and English? Lexi like Lexie in English and "Le Xi" in Chinese?
Actually Mrs. Casey doesn't really like 小扣子 (Xiao Ko Zi), so the family is now calling her "laikxi" which sounds like her English name Lexi. Lexi is from the female form of the name Alexander, which means "defender of mankind."
