Hi I've read up load on preparing formula and the more I read the more worried I get but I just don't think the guidelines are very achievable and wanted to see what most people do? At night my husband makes up a formula at 2am usher for when I feed our daughter at around 6 and if we go out fit the day we will make up a bottle but not necessarily use it for a few hours? Is this really bad as all the guidelines say you must make as you use but then you have a hungry baby waiting for formula to cool????? I get the whole use within 1 hour thing but the other stuff seems a bit excessive?
