The President of the Italian Blood Donor Association has said ‘we adopt the criterion of temporary suspension for six months after childbirth without any specific reference to breastfeeding.

In New Zealand, following pregnancy, the deferral period should last as many months as the duration of the pregnancy. The New Zealand Blood Service states ‘it is not advisable to donate blood while breast-feeding.

Whether to donate blood is a personal decision. La Leche League recommends that you consult your health care professional and/ or the blood donor programme in your country and make an informed choice.

If you choose to donate blood while breastfeeding, you need to be very careful to stay hydrated. Human milk is 87% water, and a blood donation takes 16 ounces of blood from the body. This is a lot of liquid to replace. All blood donors are cautioned to eat a substantial meal before donating blood and drink large quantities of water afterward. After a donation, donors are advised to avoid heavy lifting with the arm used to donate (to prevent excessive bruising). This may be a consideration for parents who may not be able to avoid lifting and carrying their babies or older children.
