A baby at 37 weeks is considered small for full term. When categorizing newborns according to gestational age, a term baby is defined as a newborn who is ≥37 weeks and <42 weeks, and according to this definition a 37-week baby is a term baby. Smaller babies may be the result of slower growth and development, if full-term but the birth weight is below the 10th percentile of the average birth weight for the same gestational age is known as less than gestational age, but this does not affect the classification of full-term babies. Therefore, a baby on the small side at 37 weeks is considered a full-term baby. The small size of the baby may be caused by insufficient nutritional intake during pregnancy, so it is recommended that nutrition must be strengthened during pregnancy, reasonable diet, and try not to be partial to food, so as to promote the growth and development of the fetus.
