It's not for everyone, and not everyone can (physically, financially, etc), and few that do will consistently feel 'successful' at parenting. No fidelity of a priori information will determine if it's for you. It's a leap. People shouldn't pressure others into or away from it. Governments worried about population growth should invest in social programs to aid early childcare and education; and generally improve social/medical safety nets for everyone. Under no circumstances disrupt the adoption apparatus, controls, standards therein - provide appropriate additional support around transracial adoption. The only certainty is that having a(nother) kid definitely won't repair a strained relationship.
