Congratulations: reaching week 37 means your baby is officially classified as EARLY TERM! The lungs are producing abundant surfactant, and brain development is strong.
The baby practices breathing and sucking on fingers. Although ready for the outside world, the baby continues putting on about half an ounce of fat each day to support newborn temperature regulation.
