Q: When is a baby officially considered premature? A: Although pregnancy is generally 40 weeks long, babies born at 37 weeks are considered full-term (at that point, they're developed enough that they shouldn't have any age-related health issues). Any child born 36 weeks or earlier is considered a preemie, but these days neonatal care is so outstanding that even babies born as early as 32 weeks recover very well with minimal developmental issues.
