I have been pumping at work for about a month now. I have been rinsing out the horns without drying them not thinking the tap water is getting in the breast milk until I read one of the replys here. I feel stupid and I wonder if my baby is effected by this. This means every milk she's had that I pumped at work had tap water in it. I won't be rinsing out the horns anymore. Thanks for your reply.
I also do not have a fridge to put my milk so I keep it in my breast pump bag in a baby bottle with ice packs until I get home.
