My little 5 week old c-section babe was having a lot of gas and tummy upset so I decided to try Evivo. He hates the taste so it's a little hard to get it to stay in his mouth but it seems to be helping I think. And I feel good putting good bacteria in his gut since he didn't get it from delivery unfortunately. The packaging of this product is nice. Delivery was fast and the cold packs were still cold.
