Preparing the “nest”. How does your brain change while you wait for a baby?


It’s midnight, and you have an overwhelming need to wash carpets, wiping dust off the shelves and arranged already arranged drawers. This need for sorting, cleaning, and general organization of life before the baby arrives is a familiar phenomenon that is followed by almost all future mothers and is called “nesting”.

This kind of mood can occur at any time during pregnancy, but it seems to be particularly intense in the last quarter, when many women describe this condition as “sudden excess of energy” and when future moms focus on various in home-based “projects” ,that they just have to do it before a big day.

Of course, it seems very logical to prepare your life for the arrival of the baby. However, it turned out that nature could be responsible for the urgent need to carry out all household tasks, and that such a necessity is good for mom and baby.

Pregnancy is a period during which the brain and body of a mum is busy preparing for new challenges. Research shows that women’s chemistry, even the structure of the brain, changes when the baby is born and when it connects with its newborn. However, all these changes actually begin before birth.

All pregnant women and all breastfed mothers have a high level of hormone prolactin, which is known to stimulate cognitive behavior. It sounds incredible, but the brain of pregnant women changes in expectation of the baby. Neurons grow in the region in charge of “care”, which is called the medial area, and this helps mothers to take care of their babies, but during pregnancy (while nausea and exhaustion are present), moms often channel their energy for preparing a “nest.”

Most moms describes her last three months of pregnancy,as behavior that was very unusual at times. Some moms say they literally had panic attacks if something was not done. As the mothers testifies: simply everything had to be done, almost immediately. Also, many moms agree that such behavior, or mood, was beyond their control.

Some mothers, not only feel the need to make “nests” during pregnancy, many can feel that they are under stress and entering into anxiety state. Some studies show that pregnant women have a certain level of hypersensitivity. For example, pregnant women are better at interpreting someone’s facial expressions, especially when it comes to fear and anger, which most likely prepares mothers to deal with danger, and how to best protect the baby. Another study showed that mild to moderate stress in the middle of pregnancy,was associated with a better mental and physical development of young children. It is unclear why this is so, but researchers believe that a low level of mother’s stress could be stimulating for the development of the fetus.

The “nesting” instinct is different from women to women. All of them, in the expectation of a baby, go through internal changes, knowing that their lives will never be the same as before.
