Never leave an infant alone in what could be a dangerous position. Your baby may not have been able to roll over and fall off the changing table yesterday, but that doesn't mean he or she couldn't do that today. Even playful shaking or throwing can be harmful. Give the infant safe and clean toys to hold, rattle and see. Check with a doctor about shots and growth.
Infants use all their senses to learn about the world.
They enjoy watching the results of their actions. This is how children learn, make sense of the world, and learn to communicate. When babies coo, babble and interact with others, they are developing language skills. Young children think that when they cannot see someone or something that it is gone forever. When important people in their lives leave, they do not understand that they will return.
