Breastfeeding your baby is a great way to not only bond with your baby but to give them the very best customized nutrition and antibodies that they need to be healthy. However the one vitamin that you may be lacking in providing through your breast milk is vitamin D. Vitamin D is an important part of both your pregnancy diet while your baby’s bones are developing and your breastfeeding diet as your baby continues to grow and develop.
If you do not get enough Vitamin D in your diet when you are pregnant your baby may develop a condition called rickets from soft bones. Also by getting enough Vitamin D while you are pregnant you increase your chances of having a healthy, uncomplicated pregnancy.
While breastfeeding it is important that you eat a healthy diet as your nutrient intake is what feeds your baby the vitamins and minerals they need to be healthy as well. Depending on how much vitamin D you are getting with your diet and sun exposure, you may or may not be providing enough vitamin D for your baby. If you do not have enough vitamin D in your diet, you will need to give your baby a vitamin D supplement (and you should probably a supplement for yourself too).
Vitamin D deficiency is linked to a number of factors including:
Not enough sun exposure outside.
Having dark skin
Being overweight or obese
General recommendations for Vitamin D for pregnant women by the Vitamin D Council are 4,000-6,000 IU/day. Researchers found that moms that took at least 4,000 IU a day where more likely to have uncomplicated births and their newborns were likely to have enough vitamin D when he or she was born. Women without enough Vitamin D in their diets were more likely to have premature births, develop gestational diabetes, have preeclampsia and more likely to have a C-Section.
The Vitamin D Council’s recommended intake of vitamin D for babies is 1,000 IU/day. If you are getting enough vitamin D as a breastfeeding mother, then your baby is also getting enough vitamin D and does not need a supplement. If you baby does need a supplement you can give them prescription vitamin D drops directly or add them to food or drink for your baby.
If you as a breastfeeding mother are taking a supplement of 6,000 IU of vitamin D each day, then your baby does not need a vitamin D supplement as your breast milk will have enough. If you are not taking a supplement (or you are taking less than 5,000 IU/day of vitamin D) and not getting a good amount if sun exposure, then you need to give your baby a vitamin D supplement.
If you are getting a good amount of skin exposure to the sun each day, then you are probably getting enough vitamin D to make your breast milk rich with vitamin D. However most mothers are not able to get enough skin exposure every day to meet this requirement and do need a supplement 5-6 days a week. When you are not getting enough sun exposure for a number of days your breast milk will quickly clear itself of vitamin D unless you are taking a supplement.
The upper limits for Vitamin D intake is 2,000 IU/day for babies and 10,000 IU/day for pregnant women. So, unless you are over supplementing, it is hard to exceed these limits. Formula milk varies with how much vitamin D in the formula. Most formula milk has between 40-100 IUs of vitamin D per 100 calories. You will need to figure out how much formula your child has a day to add up the vitamin D IUs they are getting. Based on this result you can figure out if you need to supplement your baby with vitamin D or not and how much to supplement. Remember to adjust your supplements as your baby’s intake of formula may increase over time.
Although exposing your skin to the sun is a great way for pregnant and breastfeeding women to increase their vitamin D supply for both themselves and their babies, you also want to be careful not to burn. Although skin exposure for your baby will increase their vitamin D directly, your baby’s skin is extra sensitive and should not be exposed directly to the sun for at least the first six months, according to the American Academy of Pediatrics. Even after 6 months you will need to be careful of your baby’s sun exposure, especially in the hot summer months as burns can happen quickly to your baby’s sensitive skin.
Vitamin D supplements are a good subject to bring up with your pediatrician. However it is also good to educate yourself on this subject as well so you can have a very informed conversation with your doctor on how to best supplement your baby if needed.
