If you want to have a second child by normal birth, theoretically it is better to wait for a year, that is, after the birth of the first child, to reach the first year of age before having a second child. But many pregnant women can’t wait for the first anniversary, and may be pregnant with their second child before they can do anything about it. If the interval between consecutive births is too close, the pregnant woman’s body is not fully prepared, such as calcium deficiency, such as anemia, the body has not yet adjusted to the second child, this is a problem. Another problem is that some people are pregnant with their second child even before they are weaned, which is not a good sign. It is best to have a year gap between the first child and the second child, which should be nearly two years, after the first child is one year old, and then nine months, which is one year and nine months apart, which is relatively better. Of course, according to the pregnant woman’s own situation, such as particularly good health, wait for the recovery of menstruation, at least 3-6 months to recover before pregnancy, because the first child after the recovery of menstruation still needs some time, some people are breastfeeding, which should be considered, it is best to wait until the child is one year old before pregnancy.
