At How Many Weeks Is a Baby Viable?
A baby is generally considered viable starting around 24 weeks gestation, when survival chances jump to 42-59%. At 22 weeks, survival rates are very low, about 5-6%, but each additional week markedly improves outcomes.
By 26 weeks, viability reaches nearly 90%. Your baby’s survival also depends on birth weight and the quality of neonatal care available.
Understanding these milestones helps you prepare and make informed decisions—there’s more to know about how every week truly counts.
