Does my newborn have a milk allergy?


The past two days she has thrown up breastmilk multiples times throughout the day(she is only 10 days old). I know milk allergies can be a common cause and I was wondering if anyone has/had a baby with a milk allergy. Her pediatric appointment is tomorrow morning so I will let them know of course, but for today I want to know what you all say. Thanks and Merry Christmas to those who celebrate it!
