My Wife does not want my Son learning coding. She wants him to become a doctor. My Son is 4 years old and he's quite fascinated with games and my ipad. I feel I should overrule her and send him for classes. How can I convince my Wife?

It is too early to tell what your son will become in future. Kids choose what they like and their future decisions. yet, if you want to teach him coding then first make sure that your wife learn some positive things about it. check this https://www.easkme.com/2015/01/places-to-learn-to-code-for-free.html.
