ELI5: Theoretically, could a human baby be trained basic manners & bathroom skills as quickly as a puppy can be, if trained in the same manner? If not, how come?

Its always fascinated me how a puppy can be reasonably house trained & taught basic commands by 4 months, but a human baby is still completely useless at that age, even though were vastly more intelligent. Why can't human babies be trained the same as puppies?

I'd assume not. Babies are born with very underdeveloped brains -  notice how most animals can stand within minutes and it takes us a year or so. This is because humans have huge heads compared with their bodies and so the brain needs to be underdeveloped to fit out of the mother's pelvis. Because of this underdevelopment, it takes longer for humans to learn many basic functions than most animals.
