The Department of Health recommends that all young children be given vitamin D supplements from the age of 1 year up to 5 years of age. There are few food sources of vitamin D so it is not easy to provide the 7 micro grams a day that 1-2 year olds require.
Vitamin D is present in fortified follow on formula and fortified cereals and there are also small amounts in eggs. Vitamin D can also be made when the skin is exposed to sunlight. However, with concerns over sun damage to the skin and the dark winters, there may be a risk of vitamin D deficiency in some infants. It's therefore important to provide a balanced diet with a suitable vitamin D supplement for toddlers from 1-5 years. Speak to your health visitor about this and they can advise you on the best supplements to use.
