I've read on here that a child might appear to be doing imaginary play but it doesn't count because they are re-enacting something they have seen on TV, like playing out a scene from Thomas or something.
So what should I be looking for to count as genuine imaginary play? If he puts his socks and pants on the floor and pretends to walk over them as stepping stones on lava does that count? Or is it more about pretending toys having conversations with each other?
