There is no doubt that Grace knows her swimming lesson exercises well. In the bath she takes Tracy (one of her dolls), hold her legs out straight and kicks away with them, then Tracy does a "chooka train" along the edge of the bath, stops and does a "bouncy bouncy on the wall, bouncy bouncy till we fall" goes onto her back, turns back onto her tummy and grabs the side. Wash, rinse, repeat.
