Girls, good evening. What can I drink besides paracetamol and Nurofen while breastfeeding? We're having trouble with our baby, he doesn't eat anything but his breast, but I can't take it anymore. He has fever, headache and muscle pain. Has anyone tried drinking something else? I can't look after the baby properly because I'm not feeling well myself.
