Death, taxes and childbirth! There's never any convenient time for any of them.

The line wryly groups three inevitabilities—death, taxes, and childbirth—to underline how life’s most consequential events refuse to align with human schedules or preferences. By adding childbirth to the familiar “death and taxes” pairing, the speaker emphasizes that even joyful or life-affirming milestones can arrive with disruption, pain, and inconvenient timing. The humor works as a coping mechanism: it acknowledges anxiety about forces beyond one’s control while inviting a stoic, pragmatic acceptance. The quote’s punch comes from its plainspoken cadence and the implied lesson that waiting for a “convenient time” to face reality is futile; one must adapt when the unavoidable arrives.
