This suggestion came from my friend Sunny on a rainy day. “You put a boy in a small bucket and see how long it takes for him to get himself out,” she explained. “In this case, he wanted to stay in there.”
Seriously, a new container that your child has never seen might inspire some imaginative play that allows you to ignore him and focus on reading clever web sites.
Put toys in the bucket. Let him eat a snack in the bucket. Turn the bucket over and stack blocks on it. Hide something under it. Decorate it with sticky notes. Roll it on the kitchen floor.
