Hello there. My baby (almost 15 weeks) was breastfed for 3 months and now we are moving onto formula as he’s a very hungry boy and I cannot keep up with his demand. We’ve tried a couple of formulas, which he hasn’t responded well to as they make him very uncomfortable and grizzly. My doctor has prescribed Nutramigen which we are slowly transitioning over to - he’s currently on 50/50 formula to breastmilk. He seems fine in the day, although he is having very frequent bowel movements. However, of a nighttime he is groaning, very uncomfortable and awake for a few hours and doing one poo after another! Has anyone else had this experience and does it get better? We are currently on day 5. The health visitor said that there’s always a transition period and best to try for two weeks. I’m just worried he’s in pain. I’d love to hear other people’s experiences. Thank you :)
