Why does formula smell like old milk?
Genuine question - is this normal or did we get a bad batch? Just switched to Similac Pro Advance and the powder smells OFF. Not sour exactly but musty? Wife says I'm being paranoid but it def smells different from what we had before (Enfamil).
That's actually normal for formula. It has a slightly sour smell sometimes, especially when it's been sitting in the container for a bit. Just make sure the powder itself looks uniform and not clumpy. If it smells rotten that's different.
