Chase says such random words!! He doesn't have words for things he needs everyday - diaper, bed, milk, cookie, etc. No, he says things like "yellow", "hippo", "baboon". He has a list of like 20 to 30 words, and these are the words that are part of the list?? :)
Chase has gotten really good lately at repeating the words when we say them to him (particularly when we are driving in the car). When we ask him to say the word "Outside" though, he says "Go"!
