When our shipment of household stuff arrived Milo got back a bunch of toys that we had packed away 10 weeks ago. Milo is a lot more dexterous now then he was just 2 months ago, but I wouldn’t have noticed the gradual development if I he hadn’t been without the blocks for so long. He’s good at stacking them now, building towers rather than just knocking them down. I kind-of got the grandparents’ view, when they say “My, how you’ve grown,” upon seeing the kids after an absence.
