When you breastfeed, milk can stay behind in the mammary glands. If this takes too long, it can lead to pain complaints and an inflammation. Most of the times this only occurs on one breast. Signs of inflammation can be: a warm, red, hard and painful spot, high fever and feeling ill. If you suspect a breast inflammation, you should let the maternity nurse watch or call your midwife.
When not all the milk is drunk, the maternity nurse will give you tips and instructions like letting your baby drink more often, massage the warm spot and warm up the breast before feeding, so the mammary glands widen a little and the nutrition can flow through more easily. By doing this, you will often prevent a breast inflammation.
