My son was also taking me to what it was he wanted until he recently started saying wanna eat or wanna drink, and open or help. He still hands me things he wants sometimes, and he won't point to something if I'm asking him to let me know what he wants, although he does point at things to tell me about them sometimes.

I also took videos, and examples of his drawings but it didn't make much difference sadly. I'm hoping that our repeat assessment right before he turns 3 will be more fruitful.
