This question is difficult to answer because sometimes there are many factors that affect pregnancy. Generally speaking, if you want a healthy baby, three months of pregnancy preparation is enough and you don’t have to be too concerned about the time. However, from personal experience, in the north of China, conceiving in June, July and August every year, the “month” of the second year of childbirth may be relatively more comfortable. Because according to the normal time calculation, the above time pregnancy, the expected date of delivery will appear in the second year between March and May minutes, this time is generally warmer weather, the temperature is not high or low, the chance of cold and puerperal infection is relatively small, and the weather is mostly sunny, for the need to enter the field to dry clothes for the newborn family is very favorable. At the same time, this time because of the warm weather, is also very conducive to the growth of infants, after a summer and winter growth, the next spring, the official start of toddler, you can better outdoor practice, which is stronger than the winter indoor training. The above is a little personal experience, I hope that friends can have a little help.
