Vitamin D deficiency is a very common problem in the UK. Vitamin D is important for good health, strong bones and growth. Most foods contain very little vitamin D naturally and it is mostly made in the skin by exposure to sunlight.
Vitamin D helps your baby's body absorb calcium, which is needed for the healthy development of strong bones and teeth. A deficiency of vitamin D can result in rickets, which affects the way bones develop and grow. The bones of a child with rickets are unable to sufficiently support their body weight, resulting in bowed legs.
The most important source of vitamin D is sunlight. Be aware that exposure of 10 to 15 minutes to the UK summer sun, without suncream, several times a week is probably a safe balance between adequate vitamin D levels and any risk of Skin Cancer. In some areas, Vitamin D is available free of charge, ask your Health Visitor.
