Re: Odkedy vziať miminko vonku?

Svinko, nevim jestli to byl tento clanek, ale davala jsem jich tu za tech 7 let co chodim nekolik...tady presne vypisuji jak a proc a jak je dite nejnachylnejsi kolem druheho mesice zivota...nejodolnejsi po narozeni...

Kazdopadne vsak je otazkou zda matka zustava doma proto, ze si mylne mysli, ze ochrani novorozence, nebo proste, ze ona sama proste nikam nechce (a je to v poradku, nemela by se nutit)...ale pak tedy je vhodne nazyvat veci pravym jmenem..


A baby""s immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus""s immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
Immunoglobulin G (IgG) is the only antibody that crosses the placenta to the fetus during pregnancy. IgG antibodies are the smallest, but most abundant antibodies, making up 75-80% of all the antibodies in the body. They are present in all body fluids and they are considered to be the most important antibodies for fighting against bacterial and viral infections. These antibodies help protect the fetus from developing an infection inside the womb.
Immediately after birth, the newborn has high levels of the mother""s antibodies in the bloodstream. Babies who are breastfed continue to receive antibodies via breast milk. Breast milk contains all five types of antibodies, including immunoglobulin A (IgA), immunoglobulin D (IgD), immunoglobulin E (IgE), IgG, and immunoglobulin M (IgM). This is called passive immunity because the mother is "passing" her antibodies to her child. This helps prevent the baby from developing diseases and infections.
During the next several months, the antibodies passed from the mother to the infant steadily decrease. When healthy babies are about two to three months old, the immune system will start producing its own antibodies. During this time, the baby will experience the body""s natural low point of antibodies in the bloodstream. This is because the maternal antibodies have decreased, and young children, who are making antibodies for the first time, produce them at a much slower rate than adults.
Once healthy babies reach six months of age, their antibodies are produced at a normal rate.
