Breast milk is best for your baby.

Health Canada, the Canadian Paediatric Society, and the Dietitians of Canada recommend that you exclusively breastfeed your baby for the first 6 months and that you continue to breastfeed for up to 2 years or longer along with complementary foods.

Vitamin D deficiencies in babies

Vitamin D is important in the formation and maintenance of healthy bones and teeth. It enhances calcium and phosphorus absorption and utilization. In fact, babies who do not get enough vitamin D are at risk of getting rickets, a disease that affects the way bones grow and develop. But do not worry, this is easily avoided by adapting your baby’s diet in the following way.

While breast milk offers the best nutrition for your baby, the average vitamin D content of breast milk is low. That is why the Canadian Paediatric Society, Health Canada, and the Dietitians of Canada recommend that all breastfed, healthy term babies in Canada receive a daily vitamin D supplement of at least 400 IU. This includes partially breastfed infants who are being supplemented with formula.

Formula-fed infants do not require a vitamin D supplement because infant formula contains vitamin D.
