Vitamin D & Your Baby
Vitamin D & Your Baby
Vitamin D helps our bodies use calcium to build and maintain strong bones and teeth.
Key points to remember about vitamin D
- vitamin D helps our bodies use calcium to build and maintain strong bones and teeth
- low levels of vitamin D in babies/children can cause rickets
- rickets can result in weak bones, delayed walking, bowed legs, and swollen wrists or ankles
- if untreated, rickets can lead to failure to grow, deformed or broken bones, pneumonia and seizures
- every year a number of babies/children in New Zealand are diagnosed with rickets
Sources of vitamin D
Vitamin D is known as the 'sunshine vitamin' because our bodies can make it from the sun. When the skin is exposed to sunlight, the ultraviolet B (UVB) rays from the sun are used to make vitamin D.
Advice about babies and the sun
Babies can't safely get the vitamin D they need from the sun. Their skin is very sensitive and should not be exposed to direct sunlight, particularly between 10am and 4pm from September to April. Many babies are likely to make sufficient Vitamin D from small amounts of incidental sun exposure (such as being carried from the car to the house). Once crawling or walking, the same sun exposure advice applies to babies as for the general population. Sun protection (shade, protective clothing, broad-brimmed hats, sunglasses and sunscreen) is particularly important between 10am and 4pm September to April).
See the following tips at the Cancer Society website:
Breast milk is the ideal and recommended food for your baby but it is not a good source of vitamin D.
Which babies are at high risk of vitamin D deficiency?
Your baby is at high risk of vitamin D deficiency if they are breastfed and:
- they have naturally dark skin
- you have been told that you are low in vitamin D
- one or more of your children has had rickets or seizures resulting from low blood calcium levels
Babies who are born preterm with low body weight may be vitamin D deficient.
Babies who are breastfed over winter months in New Zealand may also be vitamin D deficient by late winter/spring.
Supplements for babies at risk of vitamin D deficiency
If your baby is at high risk of vitamin D deficiency, talk to a health professional such as your doctor, midwife or dietitian. Your doctor can prescribe a vitamin D supplement that comes in drops.
Drops can either be:
- put on your nipple before your baby latches on
- given directly into your baby's mouth using a dropper
