Game controller for PS4

[cve60069]

Hello

I am wanting a PS4 game-controller for a five-year old. The standard controller is to large for him. I have looked on-line and there does not seem to be a controller for small hands.

Therefore, is it possible to adapt another game controller to play on the PS4 or would it be possible to dismantle a PS4 controller and make it smaller?

Thanks
