Jotting – Master Z development

Two nights in a row, when we’ve asked if Zac has had enough dinner or wants more food, he has pointed at the fridge and said “wazat” (assuming it means “want that” in this context). Last night when I opened the fridge he asked for “gert” (yoghurt). Tonight he asked for grapes – I can’t remember how he said it, but it was decipherable in combination with his pointing finger.
It blows my mind that he now had the ability to express that he wants more food and to express a preference for what type of food. Also the idea that he is remembering what is in the fridge each day – I suspect that he notices the things he knows and likes, rather than the entire contents of the fridge.
