At 22 months we've just entered the throwing and hitting stage. For "throw this, not that" I'm thinking of teaching him "hard" and "soft" and that's okay to throw soft things. I'm wondering if anyone has any insight into whether this is too complicated for his level of development.
He has excellent comprehension, mediocre word production, and very good signing. I'm sure he can learn the signs for hard and soft. I'm mostly sure he can learn what things are hard and what things are soft. I'm trying to guess whether a 22-month-old can learn "this is hard and therefore it should not be thrown."
Anyone have any pointers to studies or insights into whether this might be appropriate for his level of cognitive development?
