A mother's love in those first few weeks is so important.
I just despair at you. Parenting isn't defined by gender. Think about children who's mothers die in child birth, mothers that can't cope and give up responsibility to the fathers. Children raised by their god parents, extended family, before we even get on to same sex relationships. Being a parent is the lessons you teach your child, how it's raised, who's there for it, who loves it. Not the gender of that person.
