"Baby-shaped" diapers

I just bought a new package of Huggies, and apparently they are improved...
...they claim they are "baby-shaped". Now I ask, pray tell, what shape were they before?

L has the worst rash EVER, but she is a trooper. Has had a rough spell of diarreah, and threw up last night on her very-most-speacial-blanket. Boy, am I glad she got that flu vaccine. *I say with sarcasm*
