Can you play this on Nintendo Switch Lite?

Yes, it can be played on Nintendo Switch Lite.

How do you do the 4 player lessons? On my Home Screen it isn’t an option.

You need to get to a certain point into the main story. I think once you unlock them in the story mode, they should unlock on the home menu.

Is there a lot of reading in this game? I want to find something for my 5 year old that she can do mostly on her own.

My 6 year old just got this game as a Christmas gift. There is quite a bit of a storyline with reading in the beginning. Once in the castle, the princess is lead to a room to decorate. My daughter is getting frustrated because she can’t leave the room. The rabbit who is standing outside the door keeps telling her she isn’t done decorating. So she doesn’t want to play anymore and that is as far as she got. We will have to figure this part out.
