The reasons why a baby should be breastfed are numerous and answers vary depending on who you ask. Many new moms choose to breastfeed because it offers complete nutrition that is easy for the baby to digest, is inexpensive, and easy for the mom to provide. Pediatricians recommend breastfeeding because it has a wide range of health benefits and provides vital nutrients that meet a baby’s crucial growing needs. Some health benefits that are associated with breastfeeding are the prevention of respiratory illnesses; ear and throat infections; digestive problems; and allergies including asthma, eczema, and atopic dermatitis, just to name a few.[1]

Unfortunately, when it comes to the amount of vitamin D in breast milk, vitamin D levels tend to be quite low. Thirty four ounces of breast milk typically contains only 25 International Units (IU) of vitamin D, which is about 6 percent of the daily recommendation.[2] To put this into perspective, a newborn typically drinks 4 to 6 ounces of breastmilk per day and a one month old baby generally drinks 25 to 30 ounces per day. Clearly, breastfed babies receive very little vitamin D through breastmilk alone.

In order for breastfed babies to receive enough vitamin D to meet their growing needs, the American Academy of Pediatrics (AAP) recommends a daily vitamin D supplement of 400 IU beginning in the first few days of life.[4] However, according to Dr. Steven Abrams, a Professor of Pediatrics at Baylor College of Medicine, most babies aren’t receiving a vitamin D supplement. He indicates that “only 10 to 20 percent of babies who are breastfed are also given a vitamin D supplement”.[3]

So are low levels of vitamin D really a big deal? The answer is definitely yes! Getting enough vitamin D is crucial during a baby’s first year, when they are growing rapidly. Vitamin D is essential for the normal growth and maintenance of healthy bones and teeth. It helps the body absorb calcium and phosphorus, which are vital for growing bones and teeth.[5] Without enough vitamin D, bones can become weak or soft, and babies may even develop rickets, which leads to abnormally developed bones.[6]

Considering that infancy and childhood represent important periods of rapid growth, healthcare practitioners are looking carefully at vitamin D in these groups. Pediatricians like Dr. Abrams are seeing more health issues related to vitamin D deficiency and are concerned that there is a “mini epidemic” of deficiency in U.S. infants. He reports that a daily supplement of 400 IU of vitamin D has been shown to prevent problems related to vitamin D deficiency for almost 100 years and should continue to be used today.[7]

So is it possible for breastfed babies to get enough vitamin D naturally?  The answer is probably not. The best way for babies to naturally get vitamin D is through direct sunlight exposure. However, the FDA recommends keeping infants under 6 months of age out of the direct sun, especially between the hours of 10 a.m. and 2 p.m. This is when UV rays are the most harmful but when the vitamin D absorption rates are the highest.[8] Even when babies are outside in the sun it is recommended that they have on sunblock to prevent sun damage, which limits vitamin D absorption. All of this makes it very difficult for babies to receive enough vitamin D naturally.

This is why a vitamin D supplement is so important for infants and children. We think our Baby Ddrops® are the best way to give your breastfed baby the vitamin D they need. They are tasteless, odorless, free from most common allergens and contain the recommended dosing of 400 IU in just one drop – what could be easier!
