Getting Ready

Before jumping in to the LEGO activities (below), the kids grabbed our growing collection of bricks. Although we have a variety of sets, we always seem to pull out DUPLOs most often. They’re not too big for Big Brother (age 6.5) to complain that they’re for babies and not too small for Little Sister (age 3) to swallow them. They’re a win-win!
