Are Sony and Microsoft handing Nintendo a competitive edge by not meeting the needs of parent gamers with smaller controller options?

I have a son. I have two actually and a daughter: truly a lucky man! My first born is now five and of an age where we’ve started to enjoy playing games together. As in I play, and he watches. For the most part. With the Wii U and now the Switch, there are experiences like Yoshi’s Woolly World and even Super Mario 3D World he is capable of playing himself. But on Xbox One or PS4, there’s nothing for him. It’s not the range of games that is the problem or their complexity – it’s the controllers.
