I’m not producing enough breast milk, I’ve tried everything and it seems like my supply is getting even worse. My daughter eats 4oz per feeding and I can only pump 3 after 6-7 hrs. I know you have to transition them over mixing so they get use to it, but I don’t have enough milk to do that every bottle. Yesterday she did okay, but this morning she’s just spitting up everything. I use similac. I’m wondering if I should try one for sensitive? My first daughter never really had an issue switching over.
