It's weird to me that ibuprofen is not safe during pregnancy but it's fine while breastfeeding. I take both but try not to unless really needed while breastfeeding. I took way too much when he was first born after a pretty painful birth.I am breastfeeding and feel ibuprophen is safer then tylenol. Was really sick and high fever to point I was having trouble walking/caring for baby. 200mg took care of the fever for 8 hours and eased the aches.
