Very disappointed along with rude customer service. I purchased a two months supply for my newborn. After a week and a half of taking this he became very irritated and terribly gassy. My Ped said I need to cut out all dairy from my diet and that he probably had a cows milk protein allergy. I learned that these probiotics have dairy in them. The person in customer service tried to convince me that if he wasn’t allergic to my breastmilk that these would still be fine. Then tried to tell me to keep them for use later with him or to take myself. I don’t drink breastmilk?! For expensive as these are there should be some sort of guarantee if adverse reactions occur. Cannot recommend.
