Feel like you're living in a zoo? School starts soon (your sanity will arrive shortly thereafter) and with the first bell comes the need for a suitable back pack. Look for one that isn't too big for your little wanderer, or too small to render it useless. Skip Hop's Fox Zoo Pack for little kids is BPA-, Phthalate-, and PVC-free. The roomy main compartment and insulated snack pouch makes it obvious that this zoo animal knows a thing or two about containment.
