3. Yeah my daughter used the motion control set-up and I used the Wii U gamepad. She was pretty used to motion controls from Wii Sports, so she could handle Hyrule Warriors just fine as long as I was aware of the objectives. All she had to do was beat stuff up.
I just checked and saw the OP's kid is a toddler though. That is a tough age for video games. The only thing my daughter could play that young was 2D Mario and maybe Wii Sports (though that came a bit later). Even Mario Kart is too advanced for a toddler. 2D Mario is magic though. It really is a game for everybody.
EDIT: Actually with the guardrails setting on Switch's Mario Kart, I think a toddler could play it. Also Valkyria Chronicles is turn based but it has a real time elements to it, so that is why I suggested it.
So I got Mario Kart and just walked in on my son playing it (very poorly, but enjoying himself nonetheless), completely of his own volition. Proud parent here XD
