Your Brilliant Baby in Week 21: Matching Sound with Movement

Also realize that when you move toward your baby and then move away, he is paying attention. He's learning how the sounds of your feet change given how close to or far from you he is. He also notices how other moving objects' noises increase or decrease depending on their positioning to him. Reinforce these concepts by talking with your child about what he's hearing: "The car is getting louder because it's coming closer." "Here comes daddy! Do you hear him coming?"

Learning these sound-movement patterns now will serve your child well as he strikes out into the world and learns how bicycles', cars', and trains' respective noises become louder as they approach. In time he'll learn to move his body accordingly for safety's sake.
