So yesterday I expressed 2 and a half oz, I read online it can be kept at the back of the fridge for up to 5 days (fiancé has kindly offered to do the night feeds on friday night so I can have a rest 😍) anyway, I just took it out to show him lol and it looks like it's curdled? Is this normal? I really don't want to throw it 😫 (I'll definitely be crying over spilt milk!) but I don't want to make my baby sick!
