For those of you that have a baby with a cows milk allergy, how did you know? What were the symptoms and signs? Can it show as early as 2 months old? I'm not looking for medical advice in place of asking her pediatrician (who I will discuss it with at our next visit), I would just like to know other mama's experiences with it.

I don't know if this is my baby's problem, but someone suggested it because it seems like my 2 month old will spit up/projectile vomit after every single bottle and it's sometimes A LOT. She does this no matter if she has breast milk or formula. I googled it and she does kind of seem to have almost all the symptoms I see listed there 🥴
