1 week: unconditioned reflexes
The first week of a baby’s life is rich in skin surprises. On 2-4 days after birth, physiological jaundice of newborns may appear. This is an increase in the blood of indirect bilirubin. Physiological jaundice is a transient, self-passing (not requiring treatment) condition, which affects about 50% of full-term newborns and 80% of premature infants.
In addition, toxic erythema of newborns and infant acne may appear and disappear in the first week. Often this is a cause of concern for mothers and, as a result, a strict diet that does not cure any of these conditions. The first month, and especially the first week, is the time for the infant to adapt to new food. If in utero the baby was fed through the umbilical cord of the mother, then after birth it abruptly switches to lactotrophic nutrition (feeding with breast milk).
The thermoregulation of the child is not yet perfect, so it is easily overheated and supercooled. It has not sweated yet (sweat is a protective mechanism against overheating), which is why babies under one year old should never be taken to the bathhouse. This can be dangerous for them. You also need to remember this when planning your walks.
The first week of a child’s life is the period of lactation. Mom and baby get used to each other, the mother’s body adapts to the baby’s nutritional needs. Therefore, frequent contact with the baby and frequent attachments to the breast on demand is the key to successful and prolonged breastfeeding.
Newborn baby reflexes
Sucking reflex If you put a breast or fingertip into the baby’s mouth, the baby will begin to make active sucking movements. This is the most basic survival instinct. Helps the baby eat. As an unconditioned reflex, it disappears by about 4 months (then it is transformed into a sucking skill).
Search reflex If you pat the baby on the cheek or corner of the mouth, the child lowers the corner of the mouth down, turns his head to the side of the stimulus, opens his mouth wide and makes search movements, twisting his head from side to side. So the child is trying to find a source of food. Disappears by 4 months.
Protective reflex If the baby is put on his stomach, then he reflexively turns his head to the side. Another version of this reflex: if you sharply bring your face to the face of a baby lying on his back, he will turn his face to the side. Even in older children, this reflex persists. And adults, if they lie on their stomachs, turn their heads to the side.
A grasping reflex. The kid grabs the fingers embedded in the hand. The reflex prepares the child for the subsequent work of the hands. Disappears by 3-4 months.
Proboscis reflex With a quick finger touch on the lips of a child, he pulls his lips into a tube. Disappears by 3 months.
Reflex of support and automatic gait. If a child is taken vertically in the armpits and gently rests the baby’s feet on a horizontal surface, then he first raises one leg, then the other, as if trying to walk. Disappears by 2 months.
Moro’s reflex (fright reflex) If you hold the baby for several seconds vertically by the armpits, and then, holding his head, put it on a horizontal surface, then the child reflexively spreads its arms apart and extends its neck – this is the first phase of the reflex. The second one follows – the child brings his hands to the body (as if hugging himself). This reflex can occur to a sharp sound. It disappears completely at the age of about 7 months.
Babinsky reflex (stop extensor reflex) If you press a finger on the foot pad, the child bends his toes. And if stroke irritations are applied on the outside of the foot, then it extends the toes like fan-shaped.
Asymmetric neck tonic reflex (fencer’s pose) If the child lying on his back gently turns his head to the right, he will stretch his right hand forward, and his left bend and slightly move up. Disappears by 7 months
Galant’s reflex If the child lying on his stomach is held with his fingers from top to bottom along the spine, then he bends his back in an arc open to the side of the stimulus. Disappears by 3 months of life.
Peres reflex. If you draw along the spinous processes of the spine with your finger slightly pressing from the bottom up, the child screams, raises his head, bends his back, bends his arms and legs. This reflex causes a strong negative reaction of the child. Disappears by 3 months
Inspection of the child should be carried out in a warm room, with warm hands of medical staff. He must be full, not want to sleep. Standard situation: a sleepy baby was brought to the doctor’s office, quickly undressed, the child screamed. It’s cold in the office and the doctor’s hands are cold, as a result, the child reacts extremely negatively to the examination. It is the uncomfortable conditions for examining the baby that are the reason for making non-existent diagnoses and prescribing unreasonable treatment.
What can a child
The baby has not enough skills. He randomly moves his legs and arms. He is not accustomed to such a large surrounding world after the cramped conditions of intrauterine development.
