8 Babies Pee Inside The Womb
This is more of a weird trivia fact than something you medically need to know, but it’s a good way to gross out your pregnant friends. In the second half of pregnancy, babies regularly urinate into their amniotic fluid – yep, that’s the same fluid they drink.
You might think that urine wouldn’t be so objectionable, if all a baby is consuming is amniotic fluid, but anything Mom ingests – food, drink, drugs – passes through the placenta. The baby drinks them with the amniotic fluid and, like us, must dispose of the waste.
Since they can’t get themselves up and go to the loo, and no one’s invented in utero diapers yet, babies make do with what they have in their cramped little spaces.
