This is an important week as most of the internal organs like the heart, brain, liver, lungs, kidneys and guts have developed in their basic forms even though they have not taken their final shape as yet. The next eight days are crucial for the development of the eyes and the inner ear, which is responsible for balance and hearing. You can just about see the outer ears taking shape although they are not fully grown as yet.
The eyes are covered by a temporary skin, which will ultimately open up to create the eyelids. The tip of the nose is visible now as the nostrils have formed. The tongue has appeared and the two sides of the jaw are coming together to shape the mouth. Once the upper and lower jaws begin to fuse, the fetus will be able to open his mouth and suck or chew. But hold on right there. Your baby is not ready for toffees as yet. The baby's leg and arm bones are becoming harder and growing longer and the shoulder, hip, knee and elbow joints are forming this week. Even the fingers and toes are more obviously apparent right through the webs of skin.
The heartbeat has regularized and the pumping capacity has increased. You can see a network of blood vessels running through this little body through the transparent paper-thin skin. The face is fairly visible though the head seems disproportionately large in comparison to the body, which looks like a fish. Your baby is just one inch or 2.5cm long. And even though this tiny creature moves around a lot, you will not be able to feel him as yet.
