For the same reason that a woman can abort a child without the father's consent.
So yes, I assume that a mother can deposit a baby without the father's consent, whereas the reverse is not true.
"Any parent" means the baby can be left by any parent, but only subject to the mother's choice.
Yep, same thing with child support payments. Usually if the father is the sole custodian the courts don’t bother trying to obtain child support from the mother who has run off. Whereas the reverse is completely true.
If you’re a father that does not have sole custodianship over your child, the government court system will make you an indentured servant to the mother for 18 to 21 years.
