In a video by “simplyparenting” titled Simply Parenting: Your Newborn Baby’s Development (2009), facts were given as to the way babies react, function, and learn throughout the first few months of their life. During the beginning of their life, right after they are born, they do not do much other than eat, cry, and sleep. They are not very active. However, within a few weeks, they will begin to absorb what they see, what they hear, and the people they see most often. Newborn babies can only see clearly within eight to ten inches away from their eyes, which is about the distance between the baby and the mother or father at the time for feeding. When they are able to to see someone close, they begin to imitate their facial expressions. This happens at about six weeks. They will also try to smile at this point, but smiling will not come naturally until eight weeks of age. Babies sleep in a symmetrical position, which means that the legs and arms are lying in the same position on both sides of the body. They also hold their hands in a tight ball-like shape. A babies reflex is to grasp onto things, which is why babies react to a finger opening their hand or a finger touching their toes. They will begin to loosen their hands at about three months. Their head will be wobbly when they are pulled or picked up. This is because their muscles have not fully developed yet. The head will become less wobbly between three and four months of life. Babies can react multiple ways if a loud sound occurs instantly. They may react by crying or moving their arms in and out of their body. They also have outbursts of discomfort or crying at least once a day. This can be calmed down using a pacifier. Do not worry about the use of a pacifier. They are not harmful to the development of a baby and does not mean that they will get attached to one in the later months of their life. If a pacifier does not work, they may be able to soothe themselves by sucking on their hand or a finger.
