1. If you're a working mother, you're currently assumed to either be a bad worker, or a bad mother. (Sad corollary: If you're a working father, most people don't assume this about you.)
2. If you're a professional man, and you want children, your wife is expected to compromise her career, to raise them.
Drop the implicit assumption that only the mother needs to give up her career to raise a child.
For some reason, nobody sheds tears over successful entrepreneur, lawyer, and doctor men who are unable to make that work with raising children.
A pregnancy lasts 9 months. Raising a child takes ~200 months.
