That's a pretty condescending cliché, in my opinion and experience. Personally, I've never heard a parent say anything like that about their kid and my own kids were nowhere near that advanced at that age. Every (15-20 at the last kids birthday party I attended) parent I know give pretty realistic accounts of their child's development and are pretty humble about their own deficiencies or challenges as parents.
