My ds is 11 days old and up until 2 days ago was bfing really well and then my milk just disappeared so he was on bottles all day yesterday. My milk seemed to reappear in the evening so I fed him in the night but he stayed at the breast for quite a while then woke an hour later and took 4oz of formula so obviously wasn't full at all. Now I'm all fevery again today which is what happened when my milk came in last time but he's had formula all day again. I really want to continue breastfeeding but I can't leave him unsatisfied as that's just being selfish. Does anyone have any suggestions? I'm really upset that it's not happening for us as his latch is perfect and I feel like it's a massive loss to give up. Having a really hard time with it
