Before the baby is born, the fetus can be said to be less or less sterile because there are no microbes on the body, no bacteria. After birth, however, this changes.

In fact, every millimeter of a baby's skin is covered by thousands of microbes. By the time a child reaches pre-school age, countless populations can be found on it. By the time the baby is born, the microbes are virtually colonizing our bodies. And, depending on where we are born, we can meet very different microbes.The first dose of microbes comes from the mother. Because the vagina passes through the birth canal as the baby passes through the birth canal, there are bacteria in the baby that help to digest the first meal. Of course, babies can again get different microbes to settle on. The babies, of course, not only get from their mother, but they can get "microbes" from whatever they get. Thus, babies born at home are exposed to microbes completely different from babies born in hospitals. And these have an effect on health for months or even years.

1 day - 6 hours

Very tiny infants are most likely to colonize microbes that are found in their immediate environment or on their family members. Different populations live in different corners of the body: they are dry, oxygen-rich, and skin, so that, for example, breast milk can get into the baby microbes.

6 Hours - 3 v

By this time, the number of species will increase significantly. For example, even infants have 100 microbes and 1000 adults microbes. As children do, so do children: for example, babies get folic acid from the microbial microbes, and they take them in the fasting state of adults. Babies are more likely to have folic acid-producing microbes, while they have folic acid harvested in adults.

3 years - grown up

A three-year-old child has microbes that are very similar to those of an adult. They will also be constantly changing, reacting to events such as fever, antibiotic treatment, stress, breakouts, etc.


With the passage of time, some microbial species become more common, while others become rarer. Over the age of 65, the number of microbial species decreases. Because so many things affect our body's ecosystem, there can be many differences between populations of the same age. Just as humans' fingerprints are unique, the microbial count and composition of two human beings are not exactly the same. Microbes can be influenced by gender, nutrition, climate, age, occupation, but also personal hygiene. (Via)
