回复：北美的婴儿要补钙吗?国内是全婴皆补,心里怕怕的(在国内线等,谢谢)

For many mothers, after 3-4 months the amount of breast milk starts to decrease but the baby's apetite is still increasing.

Under age 1 you need to feed the baby baby formula (a baby at 12 month can take as much as 2 lb of formula each day) together with baby food. Then you can gradually switch to regular milk with V-D suppliments. Let the baby have sufficient sun exposure and outdoor activities each day.

Don't be fooled by all the sales pitch.
