I have mentioned before that Archie has been teaching himself new vocabulary. It’s not unusual for him to sit down quietly with the talker and methodically explore buttons, and he’ll quite often take the vocabulary he discovers in these sessions and use it at a later date.
I took a couple of videos of him exploring tonight. In the first one he intersperses exploring the talker with responding to me. In the second, after exploring for a while, he asks me to find him a specific word – and once again Icon Tutor comes in handy.
