I have a decent ish freezer supply that I have built up in prep for going back to work. just defrosted some breast milk that I froze at the end of April to use on ds weetabix as we ran out of cows milk so its less than 3 months old (this is the oldest I have used it as previously with a smaller stash it has only been rotated after a month or so).
however I noticed it had a slightly soapy smell to it which I believe can mean it's gone off?
is it possible that it's gone off after just 3 months in the freezer? we have a decent freezer and no problems with it that I'm aware of. would it be safe to use still?
