Playing in Grandpa's shoes - Callum was actually able to walk a few steps by himself. Grandma figured out why he's so obsessed with wearing necklaces - because Daddy wears a lanyard for work, with all kinds of fun things dangling from it (ID card, fob, etc.)

 No one's told me why he's such a climber, though. I never get any pictures of the steep climbs because I'm right there in case he falls (which he doesn't). Here he is surfing on the tray for his high chair. He also uses a package of paper towels as a step stool, the fridge shelves as a ladder, and tries to hoist himself into his high chair using brute force. When he was at Canadian Tire with Grandpa he found two real step stools to climb in the store.
