My 4 week old baby is on anti reflux milk and I’ve started using infacol about 2 weeks ago due to her having colic, but she’s now worse than ever! She’s screaming in pain after every feed and taking hours to settle back down. Took her to the GP they said it’s normal and to continue using both until her digestive system matures. She struggles to poo then she has really watery stool. Has anyone else had this problem?
