It's not the same feeling as I used to have with letdown. Could the feeling change? I've got no idea why the milk has increased. One side has got better and the other has got worse. It's weird. But I have been getting the odd pain just randomly through the day now
As for gulping, I'm not sure. She's feeding now and isn't gulping really. But it hurt alot when she started and got better as she fed. I'm just a tad confused by it. If it was a latch problem I'd have thought it would have caused sore and cracked nipples
