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

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
