Chapter 13: Children Who Stay Small or Have Weak Bones
Rickets
Rickets is weakness and deformity of the bones that occurs from lack of vitamin D. We get Vitamin D from whole milk, butter, egg yolks, animal fats, and liver, especially fish liver oil. The body also makes its own vitamin D when sunlight shines on the skin, but the amount it makes depends on skin pigmentation, time of year, and a person’s location in the world. Children born to mothers who didn’t get enough Vitamin D during pregnancy, children who do not get enough food with vitamin D, and children who are not often exposed to sunlight may gradually develop signs of rickets.

Rickets can be prevented by giving vitamin D to all newborn babies for the first 6 months of life (600-1200 IU of vitamin D2 or vitamin D3 by mouth once a day).
Pregnant and breastfeeding women should also be given vitamin D (600 IU vitamin D2 or vitamin D3 by mouth once a day) to support the health of their growing babies. It is also helpful to eat foods that contain vitamin D, and spend time in sunlight. Rickets is treated by giving vitamin D (vitamin D2 or vitamin D3) as well.
