thank you everyone! Its school break time here currently, she is considering stopping the OT and trying something else as the OT keeps saying one thing to the mom and another to the teacher and a third to the child and and and.
I will chat to her some more about your responses too. I will definitely bring an update as we go along.
I think the reason the mom wont see the giftedness is because she keeps comparing him to my boys, who are possibly higher up the spectrum. she also has a mom who is an old-style traditional school teacher who has always told her to not let him learn things since toddler days, and lives in an area where academic requirements are lower in level but higher in repetition. I think his learning style is also different to hers and so she just doesnt see it. I hope to unveil the wonder before her eyes if only for the little ones benefit.
