Our friend Cory came to our house for a weekend with her three year old son, and whipped out the super lightweight Baby Bjorn Travel Light Crib. (You’d think that after five years at a parenting magazine I’d have discovered this, or at least have heard about it.) Granted, the price-tag is high (around $225), but the good news is she’s been using it for three years. That’s because the bottom of the bed sits on the floor, so there isn’t any base for your kid to break. And because it’s extra wide and long, it fit not only a three year old, but also my seven year old.
