Just wanting some advise on breastfeeding and expressing etc. My milk only came through yesterday and my boobs feel really sore and full. My lil one only weighs 2.4kg so he doesnt really need that much to fill his lil belly at this stage. I am finding that he does reduce a bit of the pain when he feeds but he is only feeding on one side per feed and he is not reducing my boobs. My first son was in the nursery for a week so I predominetly expressed for the first few months giving him expressed milk because I could monitor his milk intake and then moved onto just feeding him off the breast. I dont want to express, so I was just wondering if this is normal? I am sure people dont 'have' to express and dont get mastitis. Do all newborns normally feed off only 1 side to begin with?
