Most other animals can give birth with no apparent (or just minimal) pain. But humans require help from another human and it hurts like hell!
Also, apparently, women should give birth while squatting, not lying on their backs... that just adds to the pain.
You're simply explaining why it is so - not why it is necessary. For example, another scenario might have been where children are not born with all the required neurons and developed them late on. Or that number required be actually less (most of the population doesn't seem to use half of it anyways).
Why it is necessary? heck... evolution is a crap engineer.
