I just pumped 4 oz of milk into a glass bottle, then realized I had sterilized it not recently, but almost a month ago. It was stored uncovered on its side. Do I dump it and start over? Or is the milk okay? My fear is that it was no longer sterile, and that bacteria could possibly build up in there. I would just boil the milk but I think that is a major no-no.
What do you think?
