I'm going nuts. I'm FTWM and recently everytime I checked my LO's formula, it had turned bad to a semi solid state and has a very strong sour smell. I sometimes find out after my LO drank the milk! My maid takes care of my LO in the day when I'm working, and my husband is at home more than I do. I informed them after I first found out about the spoilt milk, but I have had the luck to discover spoilt milk again a few more times after that. I'm kind of angry, but I know it's not deliberate. However, I cannot stand that it repeatedly happens even when my husband is at home more to supervise the maid. I have no idea how long my LO has been drinking bad milk before I discover it. How do FTWM manage the household by yourself when most of your time is out of home? Assuming you don't have anyone at home to supervise the maid.
