The other day Jonathan was in the backyard (his favourite place) and I needed to get him ready to go out, So I called for him, saying 'Jono come... time to go in the car', usually, I just call a few times until he starts coming to me to get ready to go, and he will often echo back 'come' or 'car'.
This time.. after a few calls.. he practicially yelled.. WHAT!!?!?!?!
I have never been so excited to hear a child talk back to me. I've told a few friends, and we all agreed, any other child would get some discusion about the right way to respond, for Jono, it was just exciting that he responded at all.
