Hi everyone, I'm a first time mum and my 2 month old daughter Imogen is on Hinz Nurture formula shes been on it from 4 weeks of age and now she seems to be getting a rash, unsettled and constipated. We went to our local gp and she refered us to a peditrician as she thinks she may be allergic to the milk, is there any advice on how to help her pain? Ive tried water,lactalose and brown sugar water. Thanks
