Yes, breastfed baby may need supplement of Vitamins D. There's a liquid form of Vitamins D supplement for infant, just needs a dropful everyday. Take the baby out for a sunbath everyday helps too (not directly under the sun, just stroll the baby around in the park during early morning should be good enough) For breastfeeding mom, Vitamins D supplement is also important, eating egg, milk, fish oil, orange juice with Vitamins D added and having sunbath can help to adsorb Vitamins D. Vitamins D is needed for absorption of Calcium which helps bone growth. Also, in recent research, Vitamins D relates to prevention of colon cancer. Breast milk is good for baby for developing her immuze system, we just need a little bit of extra Vitamins D supplement.
