I just wrote up a little list of Miss Kat's receptive words for her IEP. She now has 86 confirmed, receptive words. When I write down words, I am very cautious. I only count words that I have seen her understand in casual language (open set) and multiple time. I don't count guessing, or words that she gets only sometimes, or the ones we use in her closed set therapy sessions.
So, pre-implant she had 38. (See http://misskatsmom.blogspot.com/2008/10/miss-kats-spoken-language.html) Today her total is 88!!!! That is almost 50 words in two months!!!!!
