Is it true that a woman is in a baby's brain for three years? What is the truth behind it?

A baby's brain for three years? This sentence is widely circulated. Many women are skeptical about this sentence. Entering pregnancy, I have experienced the life course of pregnancy, childbirth, breastfeeding and parenting, and I have to admire this rumor. Always forgetting things, familiar things suddenly fail, sometimes you can't get to the point, it's easy to get into a dead end, and these things are all different. Moreover, as short as a year and a half, as long as two or three years, "pregnant fool" women will find that their state is slowly returning to normal. It seems to be refreshed, efficient, clear-headed, and better than before. In the objective test of memory and attention, there is only a small difference between pregnant women and non-pregnant women, but in the subjective feeling of pregnant women, the "fool" seems to be terminally ill.

Pregnancy will lead to great changes in women's systems. In addition to the most intuitive belly getting bigger and bigger, the metabolism, breathing and digestive system of pregnant women have also undergone obvious changes. The content of estrogen in pregnant women is gradually increasing, and the estradiol and progesterone in the third trimester will reach hundreds of times that of pregnant women. Such a big change is really a "mother" explosion. During pregnancy, not only estrogen, but also the levels of other hormones (such as thyroxine or glucocorticoid) have changed greatly. The production speed of some hormones is much higher than that in non-pregnancy period, but the body can keep the active hormones in the body at a near normal level through precise regulation and negative feedback mechanism. Pregnant women don't have to worry that the changes in hormone production during pregnancy will lead to great mental changes.

It's not easy to get pregnant and have a baby. Many pregnant women are more nervous than usual during pregnancy and after the birth of their children, and their rest at night is worse than usual. Before the baby is born, pregnant women have to have a checkup and are busy making all kinds of preparations for the upcoming baby.

After the baby is born, the mother becomes more versatile, nursing, changing diapers, singing children's songs, falling asleep, taking a pregnancy test and giving birth, and the pregnant woman's attention is completely transferred to the child. Compared with children, other trivial things in life are naturally no longer important, so it is not surprising to forget.
