Week 6 is a very busy week for your baby as it grows to approximately 5mm from head to tail. As well as growing the head, neck, eyes and ears of your baby will be formed this week. At first the eyes are far apart, almost on the sides of the head.
The baby's heart will be beating a little stronger now and he has limited circulation. This doesn't mean however that the blood pumps throughout the body, it is still too early for that. However the basis of the circulatory system is formed now and this will continue to grow and develop over the coming weeks. Although the heart is now beating it will be many more weeks before your baby would be able to survive on his own outside your body.
Did you know that your baby makes his own blood and can therefore have a different blood type from you?
The short stems which grew last week will now become more pronounced and it is here that the arms and legs of your baby will grow from. The development of the internal organs such as the kidney, liver and gastrointestinal tract is already under way and the brain of your baby continues to develop steadily. The jaws of his mouth are now formed and tiny buttons will indicate where his teeth will be formed.
