They also don't have nipples (though do have mammary glands) and mother platypuses basically sweat milk through their skin for the pups to collect off their fur

what the fuck

The milk pools in grooves on the mother's abdomen, allowing the young to lap it up.

So I guess that's partly why most mammals' milk glands are in the abdomen. Other than primates, I only know that elephants also have mammaries on the breasts

You got an ancestor that did that too. Part of why platypuses are so damn weird is because mammalian ancestors kept facing evolutionary bottlenecks. Platypuses are more like proto mammals than us placentals
