Diaper duty's not that bad. The first few months go well. Baby doesn't go that much, And the poo does not yet smell. When baby's very little, And gets fed only milk Baby's little excrement Resembles brown mustard 'til... Baby starts to grow a bit And so does baby's poo. The food they eat is more complex And they poo much more like you. Changing baby's diaper Becomes more interesting. And the smell that baby generates Starts your nose to sting. You learn real fast which foods cause Your nostrils so much gloom. And which of baby's foods are safe And don't cause deadly fumes. You also learn what kind of foods Make baby's poo too stiff. And what makes their poo so runny They could poo through a sieve. So take care of little baby And always feed them right. And be sure to check their diaper Before turning out the light.
