The nipple balm is a life saver. I also bought the cooling pads that you pop in the freezer and I found that really helpful.. I've not been sore since the first couple of weeks but I don't pump.
Thank you both. I was using the lansinoh balm and silver cups but have stopped the last few weeks so maybe need to go back to that x
It could be the pump, try lowering the setting. Lansinoh do a lanolin nipple balm which is a life saver as are silver nipple cups.
