so my coworker just seriously got in this huge argument! haha I have to pee the I swear 20x if not more while at work. and so I am telling her I have to that I pee for! and she looks at me and goes a baby dose not pee that is still growing!! my question, even tho the baby hasn't been born it still gets rid of the waste in its little body correct? she thinks I'm crazy cuz I said he goes potty in the womb!
