I did not see your post before my last comment. Do you recommend seing an occupational therapist at all? My DS6 is sensetive to things related to smell, touch, sight, sounds & taste. But has shown no vestibular or proprioceptive.
He actually is highly coordinated & walked at 8 months. So, no balance issues & no speech issues. He spoke young as well.
I don't want to waste my time or the therapists time if he is just highly sensetive due to the giftedness issue. His issues certainly do not stop us from doing things, but can slow things down.
