Hi I am using nutriprem 2 powder for my son, who was born premature at 29 weeks. He has only been on it for one week. I was using boiled water which was cooled down to room temperature which was then put into a thermos. When preparing the feed I was adding that water first then the powder. As per what I was told by the hospital which said it’s fine to do what I was doing. I am worried he may have caught a bacterial infection as for the past two days he does feed well during the day but not at night. Has anyone else ever done this? Now I’m using hot water to make am I too late.
