What is the purpose of the injection given to the baby at birth and is it really important for him to receive it?

Doctor: Vitamin K is routinely given to newborns as they have a low reserve of the vitamin, which can lead to severe bleeding. The injection is given intramuscularly as it is more comfortable for the child and is more efficient for absorption. Pain and complications are rare when given by a competent nurse. If you choose to refuse the injection, there is a risk of major bleeding. It is important to discuss this with your doctor before delivery to make an informed decision.
