Your baby is now about 20 inches long (51 cm) and approximately 7.25 pounds (3.3 kg). Most of the vernix and the lanugo that has covered your baby has disappeared. She has accumulated a steady supply of antibodies from the placenta that will help fight off infections for the first few months after birth. She continues to gain weight, although at a slower pace. Movements will also begin to slow as she is starting to outgrown her tight quarters in the womb.
At this point, all organ systems are developed and your baby is just building layers of fat to help control her body temperature.
