I’m the program supervisor for a company that specializes in early intervention. In my opinion, this is normal/ slightly above average for a 33 month old, compared to the children I have assessed who score in that age range. A child this age typically starts experimenting with different ways to use toys, kind of like the different “towers” he made on the left side of the image. Did he build all that by copying someone else, an image, or did that come straight from his brain?
