Vitamin K at birth

vitamin; k; newborn; baby; injection;;

Vitamin K helps blood to clot. It is essential to prevent serious bleeding.

Babies do not get enough vitamin K from their mothers during pregnancy, or when they are breast feeding. Without vitamin K, they are at risk of getting a rare disorder called ‘vitamin K deficiency bleeding’ (VKDB). VKDB can cause bleeding into the brain, and may result in brain damage or even death. VKDB can be prevented by giving new babies extra vitamin K. By the age of about six months, they have built up their own supply.

The easiest and most reliable way to give babies vitamin K is by injection. One injection just after birth will protect a baby for many months.
