The opposites "up" and "down" are first learnt by babies as they are picked up and cuddled by care givers and put down to sleep. As they grow older, many things in young children's world are "up", simply because they are small and have to look up to speak to adults or to reach objects they need. It is good to keep this in mind and to have their play things and belongings easily accessible. Throughout this series movement, games, songs and play experiences reinforce children's curiosity in the world around them, as well the simple direction of "Up".
