Babies do a lot of things in the womb like kicking, sucking their thumbs or making certain signs with their hands – the usual stuff.
There are however other gross things that babies do in the womb that a lot of people may not be aware of like pooping in the stomach – which can actually be very dangerous for the baby – but there’s one gross thing that could top that.
Developing babies actually drink their own pee in the uterus.
According to Romper, the amniotic fluid contains more pee than water as the pregnancy progresses. Despite the fact that the fluid is mostly made up of fluids from the mother it eventually becomes the baby’s pee.

The baby’s kidneys kick into action by their 11 week of development which makes this possible.
During this time as well, the membrane that blocks the baby’s mouth also breaks down which makes it possible for the baby to start drinking its own pee.
No need to worry however as this does not in any way harm the baby. It is just more of another thing that happens in the womb.
