Norman McLaren was a Scottish Canadian film director and a “poet of animation.” Much of his work is pioneering and playful, dancing between abstraction and representation… perfect for kids! Plus, the music is great. This is Boogie Doodle (1948).

Other short films of McLaren’s that you and the kid should see:
Spook Sport (1939)
Begone Dull Care (1949)
Dots (1940) - includes sounds that are pretty hilarious to 3 year old co-curators and 8 month old co-curators-in-training.

Also, don’t miss Pen Point Percussion (1951). It’s more of a behind the scenes look at McLaren that not only visualizes sound in a great way, but illuminates a bit of how he worked.
