If you think drinking expired OJ is bad, let me tell you what DD2 did. A couple of monthes ago I gave her a sippy cup of milk. She decided to keep it cold by putting it in the refrigerator - THAT'S HER KITCHEN REFRIGERATOR NOT THE REAL ONE
(can you guess where this is going?) !!! I forgot about the milk and a couple of days passed. She decided she needed something to drink and remembered her milk. *still get a slight gag thinking about it* She takes a sip and spits it out, chunky and all *gulp, gag, heave*, our entire downstairs smelled like soured milk. I immediately made her drink tons of water.
...Anyway, back to topic, at least it wasn't old, chunky milk.
