I'm breastfeeding my two week old baby girl and she's HATING it. She is hungry, latches fine and is mostly not fussy while feeding.

After she's done though, she is so distressed, cries and looks like she is in a lot of pain. She wheezes while she's feeding, she has projectile vomited twice but usually doesn't spit up that much otherwise, and is a very restless sleeper (often crying in her sleep).

Could this be a milk allergy? it's so hard and horrible to see her so upset She can be soothed by burping sometimes and by sucking (mostly our fingers!) Help
