Milk allergy 😢

Found out today my little is most likely allergic to milk. Now mommy has to go on a dairy free diet (that will be fun seeing as I'm married to an Italian and we love cheese and drink a gallon of milk every two days). Baby is being supplemented on Similac Alimentum too. Sigh. He's gained weight since birth but not quite enough to make the doctor happy in the last month either 😢🚫🐄
