Have you noticed that it is generally said that people who have collapsed with their children. Most of the people who are depressed are young people, but few elderly people. Why is this?

High school classmates posted on WeChat Moments, saying that taking care of children becomes mentally ill, and the picture is a registration form and a bunch of medicines from the hospital's mental health department.
Her baby is innocent and cute, and she is a typical baby who repays kindness, why does it come to this?

It turns out that she became a full-time mother after giving birth, and basically everyone was taking care of herself. The person who could sleep in the past was so anxious that he couldn't sleep all night. He was on the verge of collapse and had no choice but to go to the doctor.
There is also a mother in the same community. The eldest is in junior high school and the second child is over two years old. She takes care of herself full-time. A few days ago, she said she would be depressed and now she doesn’t want to care about her children at all.
On the other hand, I have to do housework while taking care of my children. At the beginning, I collapsed at the moment, yelled at the child. Because she made a fuss when she had to work, she slapped herself when she was angry and felt that she was incompetent. Then, the housework that I couldn't finish every day became messy again, cooking, feeding, washing pots and dishes, mopping the floor, washing clothes, and working when I was busy. Later, I gradually adapted. Most of the time it was good, and I had to collapse from time to time. I felt that I was not a god, so why did I have to do so much?

But you see that those elderly people are at ease in raising children. Do they have any magic power?
Is it because there were many children in the past, and sometimes not only had to take one, but maybe one person had to take several, but also work. I have seen all the storms and waves, so now I can take care of a child easily?
or 60 years old, I have been open to many things, and I don’t have so many anxious things. Believing that eating is fun is the king, so I feel different in raising a child? What exactly is
? Let their magic power be boundless, but I am still breathing.
