You should visit (yes you) so we can all go to Fosterfields together. We know all the animals by name except the chickens. It's great. Yesterday Peter went and stood by the back door and said "cow" until his mother took him to the farm.
He's talking more and more, and mixing sounds with signs. Still working on the final consonants, so we are Ma and Da. His favorite nocturnal raptor is an Ow. He loves when he can say words correctly, like "boo-boo". And he will kiss your boo-boo for you if invited, with a little smooching noise.
And he has been signing some complex nouns, like bird+bath and the sign for chicken which is a bird, pecking. His mom sees a lot of sentences from him but I had my first the other day at the farm when he said "pigs, sleeping."
