CAN, CAN'T, COULD, COULDN'T, DID, DIDN'T, WAS, WASN'T, WILL and WON'T - known collectively as the CAN DOs - are all friends and they each have something to teach your child. From sharing and perseverance to doing homework and being a good sport, the CAN DOs help you as a parent lay the foundations for a well-rounded, confident and outgoing child.
