  • The fingers and toes are well defined. Cartilage and bones begin to form.

  • The tongue begins to develop and the larynx is developing.
  • The eyelids are developed, although they stay closed for several months.
  • The main construction of the heart is complete.
6weeksDuring this week of pregnancy your baby is now swimming round in a little bag of fluid. The arms and legs have lengthened. They fingers and toes are forming, but are still joined by webs of skin. They can flex their elbows and wrists. They are growing eyelids as well as forming their anus. The embryo is protected by the amniotic sac that is filled with fluid. Inside the embryo swims and moves gracefully. The embryo is now about 1 inch long.

During this time of development, the baby's head appears much larger than the body because the brain is growing very rapidly. Brain waves can now be measured. The main construction of the heart is complete. Through its parchment thin skin, the baby's veins are clearly visible. During this week the ears, the teeth and the palate are continuing to form.
