I am EBF my 2 month old, and it's going very well. Recently though she has started puking, sometimes once a day, sometimes twice. It's not just a little, it's like Mount Vesuvious erupts, multiple times. Comes out her nose, soaks everything in its wake....... I had no clue she even had so much in her tummy! Is this something I should worry about? I haven't changed my diet or anything, and when my previous baby did this I switched to a gentlease formula. What should I be doing?
