As soon as Baby exits the womb, she is prone to illness and death. Baby cannot survive on her own; without care, she will die. Baby poops and pees without care for where she is or who holds her. Baby cries when she doesn't get what she wants, throwing a tantrum. Baby's instinct is not to share, but to covet and hit another baby for daring to share a toy. Baby cares only for herself. This is evidence of original sin, for Baby was born a sinner. Every sinner pays in death, but Baby is saved in Baptism.
