How do I teach my child responsibilty and to clean up after herself?

Try this simple colour-coded pickup game to make cleaning more fun: Pick a Colour and challenge your toddler to find (and put away) all the toys they can find in that Colour. "It's time to find all of the red toys! Let's see how many we can find and put away." It may take a bit longer, of course, but turning a chore into a fun lesson will be worth it.
