- Your baby is about the size of a small lime now. He weighs about 8g (0.3 oz) and he’s about 44 to 66 mm (1.7 to 2.6 in) long, from the crown of his head to his buttocks. But not for long. He’s entering a period of rapid growth. Over the next three weeks, he will double in length!
- His fingernails have formed and his external genitals are beginning to develop now. In three weeks, your baby’s development into a boy or girl will be complete. Will you find out your baby’s gender ahead of time?
Your baby’s lifeline
Wondering how your body provides your baby with all the nutrients and oxygen he needs to grow? Through the umbilical cord! It’s like a blood vessel that’s as thick as your index finger and about 20 inches long. With one end attached to your baby’s navel and the other to the placenta, the umbilical cord carries oxygenated blood to your baby and takes de-oxygenated blood and wastes from your baby back to the placenta.
