In a video by “simply parenting” titled Simply Parenting: Your Newborn Baby’s Development (2009), facts were given on how babies react, function, and learn throughout the beginning few months of their life. During the beginning of their life, right after they are born, they are not active much other than eating, crying, and sleeping. However, within a few weeks, they begin absorbing what they see, they hear, and the people they interact with more often than not. Newborn babies can clearly see within only eight to ten inches away from their eyes, which is an estimate of the distance between the baby and a parent at the time of feeding. They begin to imitate the facial expressions of a person or people they see often.
This happens at about six weeks of age. Babies may attempt to smile at this point, but smiling will not come naturally until eight weeks of life. Babies sleep in a symmetrical position, which means that their legs and their arms will be lying in the same position on both sides of the body. The hands will be held in a tight ball-like shape. A baby’s reflex naturally is to grasp onto things, which is why babies react to fingers opening their hand or a finger touching their toes. Their hands will begin to loosen by three months of life. A baby’s head will be wobbly when lifted up.
This happens because their muscles will not fully develop until three or four months. Then the head will become less wobbly. Babies can react multiple ways if a loud sound occurs instantly. Reactions may be crying or moving the arms in and out of the 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. Their use is not harmful to how a baby develops and does not ensure that they will become attached to one in the later months of their life. If a pacifier does not work, they are able to soothe the outbursts by sucking on a hand or a finger.
