On the long drive to and from Chiayi to see the inlaws, our girl likes to read books or draw. I give her a clipboard with a pad of paper clipped on it and a packet of those colored pencils that you rotate the base of to make the colored portion come out. Lately (she’s a little past 3 now) she is crazy about drawing, doing it all the time at home, including when she’s eating dinner, so that’s a good one for us.
She also likes singing songs: itsy bitsy spider, liang jher laohu, mary had a little lamb, etc. Of course you or the wife will need to accompany/lead her in the songs.
She also loves doing puzzles (jigsaw, or triangles rectangles etc that you need to arrange to fit into a box), but those aren’t good for the car because the pieces fall on the floor.
But I’ve been wondering the same thing as you. Ideally it would be something that would entertain her for a long time, not make obnoxious noises like that thing you showed, not include small parts that will fall on the floor. With those criteria in mind, I bought a rubik cube for her but I knew it was way too advanced – and it is – so it doesn’t entertain her for long. Still looking for something new.
