Where does the saying that the baby's brain is three years come from? Is this statement true?

Baby brains have been saying this since ancient times, and this statement is of course true. The so-called baby brain for three years does not mean that a woman becomes a fool after she is pregnant, but her memory drops, and she always forgets things and things.

After a woman became pregnant, she changed from a woman to a mother. A lot of things have never been experienced, and a lot of things need to be learned now. So when doing things, it always gives people a feeling of being clumsy. This is what people call stupidity.

A baby brain is perfect for me for three years. After giving birth to a son, I feel that my memory is really worse than before. After all, I'm a novice mom. I always feel strange in some places when I take care of my children, and sometimes I forget things. My husband will make fun of me and say whether I am pregnant or not, which is silly. At first, I was really unhappy. Over time, I found myself really stupid.

Usually, I take my children back to my parents' house, and I always pack my things one day in advance, for fear that I will forget my things and get into trouble. But every time no matter how I prepare something, I always forget to bring something important. I remember once, I clearly remember putting the bottle in my bag, but when I went back to my mother's house, I was going to make milk powder for my child. Turns out I didn't bring a bottle. When you think about it, it's always strange. I obviously took the bottle myself. Why?

Almost every woman who gives birth is stupid. After all, she has to take care of the children and do a lot of things. Her natural memory will decline due to serious lack of sleep. When a child grows up, his memory will gradually improve when he is about three or four years old, because he doesn't have to walk around the child every day.
