I'm always looking for little activities to keep the kids happy and busy, even if it's for a few minutes at a time. This one kept Finn amused for quite a while, working out how to stack and build with the different shaped boxes (all empty boxes and cartons from our recycling box).
He also created different shapes on the floor with the boxes, (mostly creating machines and robots). Evie (1) joined in too (mostly knocking down the stacked boxes). It was an easy activity to clean up too- everything straight back in the box.
