2.5 yr old intelligence-Is this normal???

[Momof4]

If I may give an example from my own life to enforce my earlier post, my son is exceptionally gifted, huge IQ, but as a child he was a problem. He had ADHD and learning disabilities but his IQ was off the charts. So he's in his 30's now and goes to university for a hobby, taking a phsychology or political course here and there for fun. He makes a ton of money and keeps getting promoted at his job and he's having so much fun because he's a party guy who never intends to grow up! He's freaking Peter Pan!!! What's a Mom to say to that? He's happy, he's successful, I love him, but he's never going to give me a grandbaby, darnnit!
