The story isn't about a dead baby.It's just an advertisement for a pair of baby shoes that people read way too much into.
The baby was born with abnormally large feet.
The baby outgrew his shoes before his parents ever had a chance to use them.An all too easy mistake when stocking up on apparel in advance.
The parents never actually had a babyThey bought baby supplies, but didn't have a baby because they couldn't conceive.
The parents lied about the baby shoes never being wornAnd the baby's okay. However, it is pretty dark that they were either poor or greedy enough to resort to that...
