I was delighted to find out Nintendo took the care to approach this issue the way they did.
If I had children, I would definitely buy a Nintendo Switch for them because of their focus in this aspect. Since I don't have any, I bought the Switch for myself instead. =)
I bought the switch for my 6 year old son for Christmas, his first console, because it was geared for younger kids and had these controls. <s>Unfortunately</s> it seems most of the games are really still aimed at 10+, so I've had to start playing the games with him.
My 7 year old finished Zelda several times without a lot of help (mostly early on we helped to show how to cook, etc) ... I do recommend Super Mario odyssey or Lego City though - may be more age appropriate.
Odyssey is what we just started playing, the two player is perfect because he can just control the hat, and we work together. He's just never played many video games before, apart from some Roblox. Lego is what I probably should have gotten. I bought the Pokemon game because he liked the fighting, but there's way more to it than I thought.
Its also the most pro-social council out there and its just fantastic all around. Its like they took all the greatness that was budgeted for the WiiU and pushed it off on the Switch.
