I really enjoyed Muramasa: the Demon Blade for Wii - there is some jumping and a very minimal amount of platforming, but it is 100% possible to get through the game by screeching and mashing attack (I did.)
I love Super Smash Bros. Brawl (great for stress relief and also multiple-person playing, although I will say I learnt all my best swearing from friends who played it, which may not be ideal for your small one.)
And of course there is always the tried and true Mario Kart.
I believe Virtual Console has been grafted properly onto the Wii U, so you'd also be able to pick up classic Nintendo/Super Nintendo/etc. games like Tetris and Dr. Mario to play. :)
