Childhood is a time of change. It's a time of enormous growth and development - limbs lengthen, body shape changes, baby teeth disappear and new teeth come through. This week in Play School, we explore changes in the weather, seasons, plants, animals, food and objects, in the company of familiar Play School presenters and the toys. We meet a new friend, Floppy, turn the Changes Kerchinger, greet some frogs and tadpoles and look more closely at changes through the windows: changes in the park, changes with colour, changes with insects, changes with food and changes with twins.
