All babies do not start off as a girl in the mother's womb.
Here's why:
Women only produce X chromosomes. Men produce both X and Y chromosomes. XX = female and XY = male. When a woman's egg (X) is fertilized by a man's Y sperm a boy baby is conceived. When a woman's egg (X) is fertilized by a man's X sperm a girl baby is conceived.
So the man makes a son or a daughter. The woman is unable to determine the gender of the baby. During conception there is a 50% chance of creating a boy and a 50% chance of creating a girl but either way it all depends on whether a Y sperm gets to the egg first to fertilize it OR an X sperm reaches the egg first.
Gender is complete at the moment of fertilization (conception) and then the baby (whether male or female) continues to grow and develop in the mother's uterus (womb).

^That's not fully correct
All babies do have a set gender but they do all start off with female sex organs. This is because the male organs form from chemical stimulation of the female organs. We don't know why this is.
And in cases of pregnancies at an older age, there is more chance of chromosomal abnormalities, which means the mother could be the one to create the male baby (and not the dad like normal pregnancies).
No, babies do not drink their own pee in the womb. The amniotic fluid that surrounds the baby in the womb is constantly being filtered and replenished, so the baby does not consume their own waste products.
Yes, babies do drink amniotic fluid while in the womb. This fluid helps with their development and provides them with essential nutrients.
Babies don't breathe the water in the womb. Their mothers breathe for them, and supply them with oxygen through the umbilical cord. Babies don't start breathing until they are born. Humans, well no mammal can breathe water, because our lungs can't get any oxygen from it. Although they do the same job, gills work in a slightly different manner, which allows fish to get oxygen from the water the way we get it from the air.
No, babies do not drink their own pee in the womb. Instead, they receive nutrients and oxygen through the umbilical cord from the mother's placenta. Waste products are removed from the baby's bloodstream through the placenta and are then filtered out by the mother's kidneys.
Babies drink amniotic fluid in the womb to help with their development and growth, as it provides them with essential nutrients and helps them practice swallowing and breathing.
never because they are in the womb not the belly
To get air into their lungs
placenta
Right out of the womb.
A baby comes out from it's mothers womb (which it has been in for 40 weeks/9 months) and then out of the vagina when the mother is giving birth.
yes, babies sleep in the womb but that does not mean they are always sleeping
you start out as a girl inside the womb but then develop testicals if you have male sperm
the mothers womb (uterus)
No they're mammals! They come out from their mothers womb, like every other mammal.
In their mothers' womb.
In his mothers womb
Yes, babies can sense other babies in the womb through movements and sounds, but they do not have a full understanding of what is happening.
