In winter, pregnant women can eat more seasonal fresh vegetables, such as Chinese cabbage, cauliflower, oily wheat and so on. After delivery, they should strengthen nutrition, mix meat and vegetables, and don't be picky about food. It is suggested to rest more after delivery, avoid staying up late as far as possible, ensure adequate sleep, keep a happy mood, and eat more fresh fruits in the diet, such as oranges, grapefruit and apples. Pay more attention to hygiene after delivery, keep warm, avoid wind blowing, minimize the number of outings and avoid catching a cold. Postpartum should also actively regulate the body to achieve comprehensive recovery.
