母乳喂养的孩子需要补钙么？

If you are brestfeeding, that's all your baby needs. He has got enough calcium from you. However, if you don't take vitamins, you will be loosing calcium yourself. If he is bottle fed, there should be enough calcium in formula. Too much calcium can hurt him. If his nails are pinkish, legs and arms are strong, and he doesn't have O shape legs, he should be fine.
