I'm not sure whether the size of my boobs is the issue but I'm struggling to express any milk at all even when Finn hasn't fed for ages. I have never managed more than an ounce at a time and that's from both boobs pumping for as long as the milk is flowing plus 5 minutes. I have to push the pump quite hard onto my boobs to get a decent seal and it often breaks during the pumping which I'm sure doesn't help matters. Does anyone have any tips? I'm sure my supply isn't that low although I do think it's lower than it should be hence the needing to pump and it is making my boobs sore as I'm squashing them so much for no reward.
