Hi all my little boy was diagnosed with CMPA 2 weeks ago he was given nutramigen and symptoms of rash on face and watery poo’s stopped within days. Since this he is having trouble pooing not constipation but pain and straining when trying to get it out. He is crying and tense for around an hour and then going red in the face and squeezing my hand so hard when trying to poo it finally comes out and is only a little bit but sounds like it’s tons. Anyone had anything like this on nutramigen and also did neocate work better for anyone. (He’s 7 weeks old)
