Children love to sing and be sung to and will love the repertory that includes "Pop Goes the Weasel" and "Row, Row, Row your Boat." And some - like "Pat-a-cake" and "If You're Happy and You Know It" - also help develop physical dexterity and teach parts of the body. All the songs are great for entertaining restless youngsters on car trips, on a rainy day or just for anytime fun.
