We all started as children. But a lot changes as a baby gets older. Here are some of the unique facts about the first phase of our lives.
Babies have more bones than you do
Newborns enter the world with about 300 bones, almost 100 more than 206 adults walk around with. Bonus bones are an integral part of the adult skeleton քարտեզ cartilage gaps that allow for extra flexibility և growth potential. As people grow, cartilage calcifies, and our bones merge into a whole, adult skeleton that we know we love. For most people, bone marrow transplantation continues into adolescence. At about age 16, all the extra cartilage we were born with was replaced by bone.
Most bone casting, however, occurs earlier in life. For example, “a newborn skull has many different bones that fuse over time,” says Nellie Gluzman, a pediatrician in New York. The skulls of children under two years of age have gaps in the growing bone plates called fontanelles, or “soft spots.” These openings merge into a “continuous piece of bone” at about one to two years of age.
BONUS. Although newborns have more: bones, they do not have all the bones of an adult. Newborns are born without bony knee caps. Newborn knees are just cartilage. The bone develops later.
In addition, they are transformers
Because of their unformed skeletons, children can easily change their eggs. The flexible, uneven skull of newborns is useful during vaginal delivery, when a slightly brittle head may form on the horse in the vaginal canal, resulting in a smoother outlet, which is why many newborns are born with slightly protruding heads. And our brains triple in the first three years of life. The elongated skull leaves room for all that rapid growth, says Gluzman.
In addition to having an elegant head, babies can greet the world with their legs turned inward or outward. Gluzman says. “Legs can look like frogs.” This may sound strange to those who are short, but it is a fairly standard by-product of their immature skeletons. “Very often it is normal because the bones develop over time.” They will not stay that way forever, he says, but notes that if parents are concerned, they should talk to their pediatrician.
Multiplicity comes easily to newborns
Children can drink and breathe at the same time (you can not. Probably not worth trying). Newborns are breastfed for a long time, usually for 20 to 45 minutes, staying connected by drinking milk constantly while breathing normally. The key to this superpower is the position of the baby’s throat, the muscular organ that serves as the lungs’ airway, holding our vocal cords.
In newborns, the throat is in a higher position in the throat, clogged with a soft palate to create a separation between the mouth and the airways in the mouth. This is why newborns are often considered to have “nasal breathing.” It is more difficult for them to breathe through the mouth.
Somewhere in three to six months, the throat goes down, allowing speech. But in the process of developing the vocal cords and throat of adults, we lose the ability to examine newborns.

Babies are natural swimmers (a kind)
Babies are instinctive swimmers (but that does not mean they should be put in the pool right away). From the age of six months, most babies breathe spontaneously underwater, experiencing a “diving reflex” – a series of autonomic responses that help maintain oxygen. Their heartbeat slows down, their peripheral blood vessels constrict, and they do not breathe water.
The reflex instinct to dive in most cases seems to disappear within six months. But even children with this constant reflex should never be deliberately immersed for a long time or under water. Drowning is the leading cause of fatal injury in children aged one to four years; it accounts for 7% of fatal injuries in infants less than one.
There are swimming lessons available for infants, but Gluzman says he does not recommend them; և One study found that learning swimming skills before the age of 5 had little effect on the risk of drowning.
BONUS. Newborns have many other reflex behaviors, including the well-known, super-powerful “palm violence” in which the baby automatically grasps after placing the object in the palm of the hand. This skill, which we share with most primates, disappears in about six months.
Children: to do grow like weeds
Newborns are super breeders. We already know that the human brain expands so quickly in the early stages of life that our skulls come in many pieces, but it is not just the baby part that grows fast. Babies mostly double in the first five months, and triple in a year. Six months ago, babies grew up to an inch a month.
That said, growth in the first year of life is not standardized. “Normal” size և weight is not a set number for newborns, but a series of views that form a pattern.
If the child is on the big or small side, this is usually fine. Growth recedes on the bell curve. What is more important than the initial amount is for the child to drop from the 15th percentile to the 5th percentile or move very quickly from the 20th percentile to the 50th percentile. Weight gain can be great for growing a baby, but it is even more important for babies to stay in shape, ”says Gluzman.
However, do not expect children to grow up entering the world. “It is absolutely normal for every baby to lose weight when it is born. “Weight loss of 10 percent or less immediately after weight gain is normal,” says Gluzman. And babies need to gain that weight within the first two weeks after birth.
The taste of food is different in early life
Children taste food differently than older children and adults. People can detect the sweet-sour taste when we are born, ությունը prefer the sweetness of breast milk right outside the gate. However, some studies suggest that babies do not experience bitterness for up to 2-3 months. And newborns do not seem to take the saliva for 3 to 4 months.
Although it takes time for a baby to fully develop tasting, newborns have more taste buds in more places (such as on their glands) than adults. These taste buds begin to develop in the uterus, և the fruits take on the aromas that float in the amniotic fluid. The CDC recommends that infants be introduced to foods other than breast milk or formula for about six months. According to Gluzman, in these early food intakes, infants may prefer what their mothers ate when they were in the womb because of a familiar taste.
And all newborns tend to start as selective eaters. It can take many introductions to a new food before the baby takes it. Getting a new food requires an average of 7 foods, says Gluzman. So, even if the child initially rejects it, keep pushing that broccoli, they can learn to love it.
Babies do not need to drink water
In fact, moisturizing with water is dangerous even in the first months of life. Babies get all the hydration they need through breast milk և formula, just as these ingenious fluids meet all their nutritional needs.
Breast milk and formula are the claims of sports drinks. Electrolyte balance. They contain the perfect blend of water and salts to keep you healthy. Giving water to a baby under the age of six months can compensate for this imbalance, leading to low relative sodium or dehydration. Newborns have immature kidneys that cannot filter excess water as efficiently as adults do. This excess water eventually floats in the bloodstream, diluting the blood and reducing the concentration of important electrolyte molecules that aid in cell communication.
Gluzman explains. The water also fills, և the children have a very small stomach. The baby’s stomach is the size of a marble. Although the stomach begins to grow rapidly, water can easily fill the baby և take up space for the baby’s calories և nutrients:. He says feeding infants who are 6 months or more short of water “becomes a big risk for something called failure.”
Our first jokes do not stink
The substance that newborns excrete is called meconium, the uterus from the nutrients that are still taken in the womb. Meconium usually has a very low odor և usually passes within the first few days after ejaculation. Some babies are even born covered in meconium. This can happen if the baby is stressed և passes meconium while still in the womb.
The pungent odor is mainly due to our intestinal bacteria, the by-products of those bacteria that help break down food. Newborns leave the uterus without a colony of bacteria in the gut. Intestinal colonization begins in the birth canal, continues around the world through breastfeeding or artificial drinking, and after a few days of formula or formula, the baby will begin to produce a balloon that looks and smells different from the original number. two
Babies drink milk, and sometimes they make it too
Newborns can breastfeed, which is perfectly normal. Neonatal galactorrhea, the scientific name for the phenomenon, occurs in about 5% of newborns. And all babies, regardless of gender, can experience it.
Infant lactation, however, is different from normal lactation; it is usually a very small amount of milk that comes out of the baby’s pacifier. This is due to the high level of estrogen in the uterus ազդեց breast milk և generally resolves on its own. However, new parents should discuss this with their pediatrician, especially if the neonatal galaxy lasts for more than two months.
Newborns are born with terrible eyesight
All babies start with a horrible vision. In the first few months of life, says Gluzman, babies have a very close field of vision. “If the mother is breastfeeding, they can see her face, but more is not really possible,” she explains.
Concentration of the eyes leads to the muscles, and the baby’s brain must learn to process visual information before it can do so accurately. When children reach the age of five months to one year, they can see farther, more accurate objects.
And from the beginning, babies respond much more to high-contrast, black-and-white images than to bright colors. Although it is possible that newborns can still see color, they do not develop color at all until a few months later. When vision develops slowly, babies begin to respond to more colors, usually starting with red a few weeks after birth.
