So this week I have started trying rice cereals with my 6 month son and was mixing it with breastmilk. The second day I discovered that the pumped milk in my fridge that I warmed up for him smelled sour! I tried it, Yup, tasted AWFUL! so I dumped it. Since then I've had to dump many bottles of hard earned milk that I had saved up for extra top ups or mixing with cereal. admittedly I hadn't been meticulous about boiling my pump parts and bottle EVERY day, although my storage bottles were all clean, and the milk had been in the fridge for max 3 or 4 days only, and had gone straight in. So I machine washed everything and then sterilized for 20 minutes, and the first bottle I pumped I put in the fridge, was in there for 1-2 days or so before I used it, warmed it up.. still smelled sour!!! this is VERY discouraging!
I've done some research last night and read that some women's milk goes sour more quickly because of an increase in lactase or something, and that scalding quickly on the stove top after pumping can help. Anyone with expereince? am I alone here? any suggestions or stories would be appreciated! I can sometimes get a fresh smelling bottle if I just leave it in overnight, or pump fresh, but I have low milk supply and usually don't have a lot to spare to pump fresh in the daytime, only at night after babe is in bed. so my milk is precious to me!
Also. it smells bad to me, but if the milk really hasn't been handled wrongly or left out too long, is it really bad for my baby? I actually tried to feed him a bottle that smelled bad to me yesterday (only an ounce, a day or two old) and he took it no problem! I thought if it was bad, he'd refuse. Did I feed him sour milk? does it really matter if he doesn't care? HELP!
