Is it true that when we are a baby in our mothers womb, that we are actually breathing in water?

the baby is in water in the womb, breathing without any problem, upon being born the baby is able to go through the transformation to breathing in air instead of water. if this is true then why can’t we jump into the water and go through the reverse transformation, and start breathing in the water? No one seems to be able to do it,
everyone seems to drown. But still, it seems like it could be possible….,if the baby can do it…., i’m probably missing something somewhere here huh?
