Does my baby need a Vitamin D supplement?

Rickets is a serious condition arising from vitamin D and/or calcium deficiency, and affects the development of bones in children.

Rickets, a condition that affects the bone development of children, is most common in babies between the ages of three and 18 months. In South Africa, this condition is most prevalent in babies and children who are either exclusively breastfed by mothers who are vitamin D and calcium deficient, kids who are fed an inadequate diet, or children who are kept indoors for long periods of time without being exposed to sunlight.

Symptoms of rickets

According to, signs and symptoms of rickets can include:

  • Delayed growth
  • Muscle weakness
  • Pain in the spine, pelvis and legs

Because this condition causes soft and weak bones, it can cause skeletal deformities such as bowed legs or knock knees, thickened wrists and ankles and breastbone projection.

What causes a vitamin D deficiency in babies?

Our bodies produce vitamin D after the skin is exposed to sunshine. Ideally, a baby shouldn’t be in direct sunlight during the first six months of life, so he won’t get enough vitamin D from the sun – even if you live in a relatively sunny place like South Africa. Another cause of vitamin D deficiency is an unbalanced diet, lacking in calcium and vitamin D.

When does a baby need a Vitamin D supplement?

In most cases, breast milk or formula provides just about everything a baby needs for the first four to six months. However, the exception is vitamin D, which is why the American Academy of Paediatrics (AAP) now recommends that you give your breastfed baby a supplement of 400 IU per day of vitamin D, starting in the first few days of life. Babies who are fully or partially formula fed, but drink less than 900ml of formula a day also need a daily 400 IU vitamin D supplement.

How is rickets treated?

Most cases of rickets can be treated with vitamin D and calcium supplements. Always follow the doctor’s directions as too much vitamin D can be harmful. A child’s progress will be monitored with X-rays and blood tests and more severe skeletal deformities may require surgery.
