We have officially stopped tracking Simon's words.
We tracked his first 100 words and I am quite happy with that. Around the end of January he started learning many new words a day and by now he can repeat and say words that he just heard us saying and we weren't trying to teach him. It's amazing how saying the first 100 words was a slow road and now the learning is exponential.
Some of the fun new ones are 'Where are you?' said in a sing song voice whenever he's looking for someone or something, Oatmeal (said as two distinct syllables) and Daddy-o (said with a serious pause at the hyphen) are some of my favorites.
In general he is a fantastic little communicator. When he is hungry he goes to the kitchen signing 'hungry' and then says eat or cook (or more often snack!). Then you give him a list of options and he'll tell you what he's in the mood for - though sometimes he just cuts to the chase and tells you banana or egg or yogurt before you can even ask.
Now it is on to the next 100 words... we'll be there in a couple weeks I think.
