I agree with nhockaday. Try dfferent things. My grandson 2 yrs 7 months spends most of the time playing with animals and even when coloring he prefers animals. When playing with cars or blocks he changes to something else very fast.
... My nephew loves our laptops so one time i played an ABC game with him. he wanted to play it again and again. he was learning and sitting still
Ariel do you remember the link to the ABC game?
