Why is cause and effect so important? Developing cause and effect is important as your baby learns that his behavior and actions result in a response from a parent. For example, when you're in for a prize, respond by picking you up, changing, or feeding him. Your response to your child's early communication is important for him to learn the cause and effect relationship. Later, babies begin to explore objects such as shaking a rattle to hear a sound. This is your child learning that shaking causes the sound. The cause and effect relationship develops your child's cognition exploring the world. Learning how to make things happen is the foundation of problem solving. Your child will learn that when he calls, you will come. Babies will begin to explore cause and effect toys by pressing buttons and shaking and batting. You can encourage your child to explore cause and effect relationships by offering toys. Babies will also discover object permanence. Object permanence means that the child knows and objects still exist, although they can't see it. So by dropping objects from their hide share and waiting for your response to pick up the objects, they are demonstrating object permanence. Toddlers will begin to solve problems using cause and effects by opening and closing, trying to flush the toilet, stacking, and knocking down blocks, pushing buttons and pushing cars.
