Who thought it would be smart to have over-the-head clothes for babies?

Quite aside from how challenging it can be to get something over the head of an infant who cannot yet control said head, didn't this person think of what happens following a diaper blow-out?

Oh, maybe that person's baby never had containment failures. And that person's baby only pooped out sweet-smelling rose petals and peed out holy water.

Yeah, that's got to be it. Because nobody who has ever had to manoeuver a poop-soaked onesie or bodysuit over their child's head would think that this design was brilliant.

But the question remains: why do we buy these items??

(Oh, right. They're damn cute.)
