At 6 weeks the baby is the size of a pomegranate seed!
An ultrasound may pick up a tiny heartbeat of about 105 beats per minute.
The brain and nervous system are quickly developing. The neural tube begins to close over what will become the spinal cord.
There are now little bumps that will become eyes and ears. Tiny buds are forming – future arms and legs.
The nose, mouth, and inner and outer ears are just starting to take shape, along with the lungs.
Soon, breathing tubes will form between the throat and the lungs.
