Your baby has a face! Your baby's features are becoming more predominant as his lips, tongue and nostrils, as well as the buds for 20 baby teeth are already present. The back muscles are growing along the spinal column, and his or her reproductive organs have started to form and soon will become either testes or ovaries. The arms and legs are growing while elbows and knees appear as well. The fingers and toes are starting to show but are still webbed. Your baby is about 8 - 11 mm or 0.31 - 0.43 inches in length.

The process of ossification (hardening of the bones) begins as the bones of the fingers and toes have already reached the first joint. Your baby is already getting smarter as his brain continues to develop and grow. Your baby starts to show signs of reflex activity - an automatic response to certain types of stimuli. Connecting you and your baby, the umbilical cord with all its blood vessels, are starting to function. In fact, what will be your baby's intestine is forming in the umbilical cord as well. An ultrasound done this week would show your baby's fluttering heart and reflex movements.
