Signs of normal development in the newborn

Posture and movements

• His posture is symmetrical and fairly rigid.
• When his back, his head looks straight ahead, arms and legs are bent over the body, so that the beads do not touch the bed. He makes sudden, involuntary and uncoordinated movements.
• Face down, knees are bent under her abdomen. only able to raise his head just enough to turn it from side to side.
• If you are up estirándole arm, hangs her head and arms and legs flexed maintained.

Reflexes

The newborn has curious reflections pediatrician explores the first reviews to ensure normal and proper development of the nervous system. Some, such as sucking, you are of course very useful. Others are a sign of his neurological immaturity and should lose over time.

Search. Also called "reflection of the cardinal points" when something touches the corner of his mouth, turns her head and opens her mouth looking in the direction of the stimulus (or at the cardinal point where he has played). This will be used to start the shots and, like all reflections, is an involuntary movement.

Suction. To a contact in your palate reacts sucking. This reflex does not fully mature until 36 weeks of pregnancy, which explains the difficulties that premature may have to suck vigorously and effectively.

Moor. Normal for the first three or four months and named in honor of its discoverer, also known as startle reflex, because this is how it is caused. The pediatrician often explore letting his head drop sharply back, causing him to open his arms and legs, then finally mourn and limbs back to its original position. it can also trigger a sound, including the baby's crying himself.

Tonic neck. To five or six months, turning his head to one side, the arm on that side stretches and the other is bent at the elbow, taking what pediatricians call "fencing" position.

Understanding. By rubbing the back of his hand, his fingers close tightly. In preterm it is so energetic that allows them to stay in the air hanging from the finger scanner. Lasting up to four months.

Automatic start. To the first or second month, you may get to hold him take a few steps with his feet on a flat surface.

senses

The baby is born with the five senses and is able to react to pain, heat, cold and even to distinguish sounds, smells and tastes.

View. The eyes begin to develop four weeks after fertilization, and four months pregnant, are already sensitive to light.

• At birth, the baby is able to see the light and distinguish colors, perceiving contrasts, movements and sudden changes in lighting. You can look at the faces and bright objects in their visual field.
• Focuses what you are 20 or 30 cm from your eyes, that is, the distance that normally face their parents is when you have held.
• In a curious experiment, it was observed that with 10 hours of life, spent more time without looking pictures normal faces when they were aggressive.

Ear.The fetus perceives sounds and mothers will notice kicking or moving to loud noises. The newborn already has the ear fully developed.

• Within a few hours of life, their heart rate speeds more so the more intense sound.
• Pay special attention to the human voice and, according to some studies, it seems to prefer the high tones of the female voice to the serious own men.
• During the first few weeks, you can react to sounds with a very spectacular start and getting to mourn (Moro reflex) or an almost imperceptible change of activity, blinking, or by not sucking or breathing for a moment.

Smell. From the first day of life, the baby reacts to smells. It has been shown that discriminates between anise odor and onion, and the latter makes it away. Another study is able to recognize the smell of their mother to the point that on the sixth day you recognize your chest between other women precisely because of the smell.

Taste. Underdeveloped at birth, matures very quickly, so that a fortnight, the baby already shows your preferences. He rejects faces and movements of the tongue extrusion acidic and salty flavors, while reacting positively to sugar, licking his lips.

Touch. It is the first sense to develop. The skin around the mouth is sensitive to eight weeks of pregnancy and above 20 weeks, which is already the whole body. The newborn is very sensitive to the way he touched and handled, and physical contact is the earliest and most primitive form of communication and a critical element in bonding with the baby.
