You can’t grow taller by having children. This is because theoretically, once the body has finished growing, the epiphyseal cartilage within the long bones ossifies and becomes normal bone, at which point the long bones lose their ability to grow and the body loses its ability to grow taller. Some people claim that there is a certain degree of height growth after the end of labor. This may exist, however, it is not due to bone growth, but often due to the fact that the spine remains in an extended position after the end of labor, which then causes a certain degree of height growth. Since you have to hold your belly for a long time during pregnancy, your spine will remain continuously extended, and you may still maintain this posture habitually after delivery, and your body will look more upright, and you will grow 1-2 cm in height when you measure your height. However, this growth will gradually return to normal with postural changes and future weight-bearing walking.
