I exclusively breast feed my son when I'm at home and while he's at daycare he gets expressed breast milk. My sitter noticed this week that my some of my milk is starting to smell 'spoiled' and that my son won't drink it. I'm not sure why this is happening since he always gets fresh milk. I pump at work and keep the milk in a refrigerator. I started doing a smell test when I prepare his bottles and this morning one that I pumped yesterday smelled yucky and the one smelled off (not yucky but off).
Has this happened to anyone?
Sometimes, I have a cappuccino in the morning or a decaf coffee (just started this a week or so a go), the only other changes is, i don't clean my parts after every pumping session (i pump every 3 hours at work). I just rinse them and put them in my cooler in the fridge.
Could any of this be effecting it?? suggestions?
