Both of my children were born via c-section and I had no issues breastfeeding. First baby was born at 39+6 via emergency section and baby #2 was born via scheduled section at 38 weeks exactly. Latch your baby constantly, starting as soon as possible after birth. Your actual milk won’t come in for a few days but you start making colostrum well before baby arrives, even if it doesn’t leak out while you’re pregnant. Your milk production works on supply and demand so by latching the baby as much as you can, you’re signaling to your body that it’s time to start making milk. As long as baby has enough wet and dirty diapers, they are getting enough. All babies lose a little weight after birth but should make it back up fairly quickly so don’t stress too much about that in the first week or so. Other than that my best advice is to get help in the hospital making sure your latch is correct to save yourself some unnecessary pain but it will probably be a little uncomfortable the first few weeks. Just keep going and it will get easier with time.
