Throwing my theories onto the fire asto the science of mythical horse-butted babies.
nO THIS WAS NOT an excuse to draw tiny chubbly-wubblum baby Clyde and lanky knobbly foal legs. NEVER.
FOR SCIENCE! Like gestating in the horse half would mostly remove the limitations of the human pelvis that restricts the size of a babies head so a foalby could be born mostly ready to go with just a small period of intensive care that human bebes require. Also adding unique behaviors while solving my personal problem with wtf centaurs do with their hands/arms when running. Obviously they wouldn’t do the tuck and run all the time but if you’re scared you don’t want extraneous limbs flapping about throwing your balance off if they weren’t necessary.
