Aiyoh first-time mum struggles, I feel you! The main thing is proper latch, baby's mouth should cover more of the areola, not just the nipple, and make sure the latch feels comfortable from the start (if it hurts, break it and try again). A few of us tried different positions like cradle hold or football hold to find what works best for our body, plus keeping nipples moisturised between feeds really helps, I used Mama's Choice Nipple Cream (it's safe for baby and breastfeeding) and honestly made a difference within a few days. Don't hesitate to see a lactation consultant or your doctor if the pain doesn't improve, because sometimes there's a tongue tie or other things that need checking. You got this, mama!
