宝宝从出生到一周岁为婴儿期。婴儿大脑及身体各组织器官发育极快,对各种营养素的需要也很高。然而婴儿的消化系统虽然在形态上与成人相似,但其胃肠功能尚不健全,消化能力较弱,所以,婴儿饮食种类及数量均受到限制。因此,要根据月龄的增长情况,给予不同的饮食。 0～2个月:此期婴儿具有吸吮,吞咽的能力,消化系统发育不完善,适应能力较差,应尽可能地采用母乳喂养。为补充维生素A和D,可从出生后2周起即可逐步添加适量浓缩鱼肝油,母亲可多吃些水果和蔬菜以增加母乳中的维生素C,亦可直接添 Baby from birth to one year old for infancy. Infant brain and body tissues and organs develop rapidly, the need for a variety of nutrients is also high. However, although the infant’s digestive system is similar in morphology to adults, its gastrointestinal function is not yet complete and its digestive capacity is weak. Therefore, the type and amount of infant’s diet are limited. Therefore, according to the growth of age, give a different diet. 0 ~ 2 months: the baby has the ability to suck and swallow at this period, the digestive system is imperfectly developed, and its adaptability is poor. Breastfeeding should be adopted as much as possible. For vitamin A and vitamin D supplementation, appropriate levels of cod-liver oil can be added from 2 weeks after birth. Mothers can eat more fruits and vegetables to increase vitamin C in their breast milk.
