So I feel that the main reason why pregnant mothers walk like penguins after pregnancy is obesity, because I didn't have this phenomenon in the early stage of pregnancy. About half a year later, one day my mother and I went shopping. My mother said to me, "I've really gained weight recently and started walking sideways."
Only then did I know that it was really difficult for me to walk at that time. I was particularly depressed at first, because it was really ugly. But you can't go on a diet at that stage and eat more later.
I don't care about it slowly, I can only reduce the chances of going out every day, because the older the children are, the more tired they are, and it will be particularly tiring to go shopping later. Plus, they are getting ugly and don't want to go out.
Maybe after this experience, I paid special attention to women's walking when I went out, and gradually found that as long as I was fat, I would walk a bit like a penguin, but my mother was more like it. The reason should be that my mother is pregnant, especially in the late pregnancy, and I need to walk with my stomach on my back.
