My friend came by today with her three week old, and all the stuff that comes along with such a small baby. Kiddo was excited to see what was in her huge diaper bag. Before too long she came across the tupperware of powdered formula.
"What's that?" she asked.
"Formula," I answered. "You don't need it," I added as she tried to open it.
"Formela" she repeated, trying to get the feel of the new word.
"No, for-MU-la" I asserted, so she could get the word right.
"For-ME-la" she repeated.
As we went through the correct word, and her repetition, the third time, I was gratified to learn that she understands first and second person. When I say "you," she says "me."
