Girls, maybe someone has encountered such a problem. We've been at it for two months. Poop is straight green swampy, once a day. On S.V. I give enterosorbents. Since birth, I gave her enterosorbents. There were strong colic, straight all day crying. And warm application and dill, and beans all that stuff helped, not very much. Then we decided to change the formula, because I have lactose intolerance, took the baby without lactose-free formula. Seems like it started helping, less crying, BUT, poop is still green. The therapist says the formula doesn't suit him. But I see that he feels better with it. How can you check who to contact?
