Re: What do you think about this co-worker?
Mama, I'm so sorry this happened to you! And in L&D, too, where people should know better.
First of all, "Bertha" is a . Your breastmilk is like urine? Only if cow's milk is like cow urine. In your shoes, I'd be strongly tempted to fill a sample cup with apple juice, label it with the word "urine" and nestle it up against her lunch bag.
So, should you just cede the fridge and bring an ice chest for your milk? Well, honestly I think the answer is yes- but not because breastmilk is gross and you should hide it away like it's shameful. I think you might want to find a different way to store your milk because refridgerators are gross. DH once asked a microbiologist friend of ours what the dirtiest place in the house is, expecting that he would say "The toilet, duh!" Instead, he said "It's the fridge, man. You don't even want to think about what's growing in there."
But you should not have to cede the fridge to the anti-breastmilk bigots. They are wrong and you are right, you did exactly the right thing to go to HR, and hopefully HR will come up with an appropriate, family-friendly policy. If there's any justice in the world, you'll get a brand new, spanking clean fridge with a sign on the door that says "Breastmilk only, no food. And that means you, Bertha."
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
