My 6 week old son began spitting up A LOT at around 3 weeks. I began taking steps to help with reflux as well as a milk allergy - so I was dairy free for a few weeks. When I went to the pediatrician on Monday, he told me it seemed to be reflux and not a milk allergy, so to start re-introducing milk into my diet. Well, last night I had some cheese at dinner (he seemed fine) and then today I had some milk and now he's been spitting up a lot again (like it seems like his entire feeding). So now think it's the dairy and I feel sooo bad and I don't know what to do. How long will it take for the majority of the milk protein to be metabolized and out of my breastmilk again? Should I pump and dump in the meantime (I only have enough stored milk for 5 feedings since I'm at home with him and just started pumping). Any advice would be greatly appreciated.
