People without children have no idea how much energy parenting takes, especially in those first few years. No idea.
Don't discount that some people struggle with the object of parenthood more than others. Maybe they'd led a more selfish life, weren't brought up to be yielding, giving, or responsible to others, and their journey required more growth than they'd anticipated.
