Dreaming of breastfeeding a baby can symbolize nurturing, care, and a deep emotional connection, often reflecting your own nurturing instincts or responsibilities. The presence of an IV in your arm that causes pain might indicate feelings of vulnerability or a sense of being drained, either emotionally or physically.

This dream could suggest that you are giving a lot of yourself to others, perhaps at the expense of your own well-being. It may also reflect concerns about your own health or the health of someone you care for. The pain associated with the IV could symbolize discomfort with the way you're currently managing your responsibilities or relationships.

Consider reflecting on areas in your life where you might feel overextended or where you need to focus more on self-care. It might be a good time to evaluate how you can balance your nurturing side with your own needs.
