First of all, we should pay attention to keep warm, because pregnant women are generally weak, so the first step in their health care is to keep warm.
Secondly, we should pay attention to diet and nutrition. Pregnant women already have a lot of taboo foods that can't be eaten, so when they are healthy, they should pay attention to supplementing nutrition, eating more fruits and various foods rich in vitamins.
Finally, we should do proper outdoor sports and take more walks. Proper exercise can improve the immunity of pregnant women, strengthen their physique and improve blood circulation. Therefore, pregnant women can go to the park more often for health care.
