Trey says "nose" when he wants me to blow his nose, and "diaper" when he needs a diaper change. He practically takes care of himself!
I just realized tonight that "dah" means "yes." I think he got it from Joe and I saying "yeah."
Someone taught Trey how to say "baby burp" and "baby toot toot." Now after we giggle about it, I am trying to repair the damage and teach him to say "excuse me!"
