Babies
New born babies are dependent on others.
They do not know how to work their muscles or control their physical movements. Their nervous systems are not fully developed and they can only see objects clearly at about 20cm.
Over the next months all this quickly changes. By four months most babies can sit with support and hold their heads up for short periods of time. By six months, most can sit without support and by eight months most can pull themselves up to a standing position, stand with support, and walk if supported and led.
During those first months of life other exciting developments are occurring that are easily taken for granted. They are starting to become aware of some really basic but critical concepts. First, they are starting to become aware that they are separate from their parents and that their parents love and value them. Second, they are learning they can trust their parents to feed them, provide shelter, protect them and to give them pleasant feelings. Third, they are becoming aware that they can respond to their parents emotions and that their parents will respond to theirs. They are three pretty obvious facts but are fundamental to the baby's development into a mature human being.
