I am all in favor of making it as easy as possible for mothers to safely abandon babies that they do not want. There are long lists of loving prospective parents who would gladly take full and lifelong responsibility for any babies that are not wanted by their birth parents.
The mother of the baby not wanting to raise the baby does not mean the father of the baby not wanting to raise the baby.
Mothers of babies should not be legally entitled to abandon babies with out the permission of the fathers of the babies.
