So my four week old has been on Aptamil, both the liquid version and the powdered version, since birth. Originally we were just giving her liquid due to having been given loads of bottles and due to our prep machine making 4oz on the smallest bottle; which she wasn't taking that much in one go at the time. Once she got to 4oz we started using the powder and ever since she has been struggling to go toilet. She was okay the first week or so but since has been going every two to three days.
Please could I have som advice on experiences with formula? Has anyone experienced the same and what did you change to? Unfortunately unable to breast feed as she wouldn't latch due to inverted nipples!
