Mia's Vocabulary at month 18

I calculated Mia's vocabularies today by Chinese and English. She's been able to name objects and expresssions: a total of 100 words/phrases in Chinese and about 50 in English. I am acutally quite surprised. Lately I've noticed a marked improvement. Last time I couted was about 3 weeks ago, at the time, I was able to count about 60 words in total. She has now more than doubled her mastery of language. I find it much easier to communicate with her now. She even told me about her earache several times, leading us to go to the pediatrician to treat her ear infection.
