Pregnancy development slideshow
Pregnancy slideshow shows how a baby develops during every stage of pregnancy from week one to the birth. Understand what happens during pregnancy.
Size: about 4mm 5 weeks pregnant The cells fold up and round to make a hollow tube called the neural tube. This will become the baby’s brain and spinal cord. By the end of this week , blood circulation will begin and the heart will develop quickly. the woman “misses” her period.
Size: about 7mm 6-7 weeks pregnant The brain is developing distinct areas, and the eyes and the ears are beggining to take shape. The heart begings to beat and can be seen beating on an ultrasound scan. Small swelling called “limb buds” show where the arms and legs are growing.
Size: about 8-10mm 8-9 weeks pregnant The baby is now called a foetus, meaning ‘ young one’. The face is slowly forming. The eyes are now more obvious and have some colour in them. There are now the begginings of hands and feet, with ridges where the fingers and toes will be. The major internal organs are all developing.
Size: about 22mm 10-12 weeks pregnant Just 12 weeks after conception the foetus is fully formed. By now, almost all of the baby’s organ and structures have formed and will continue to grow until delivery. The baby is already moving about, but the movements cannot yet be felt.
Size: about 85mm 13-20 weeks pregnant The baby is now growing quickly. The body grows bigger so that the head and body are more in proportion. The face begins to look much more human and he hair is beggning to grow as well as eyebrows and eyelashes. The eyelids stay closed over the eyes.
Size: about 15cm 21-24 weeks pregnant At about 22 weeks the baby becomes covered in a very fine , soft hair called lanugo.The purpose of this is not known, but it is thought that it may be to keep the baby at the right temperature.It may be possible to feel the baby move for the first time.
Size: about 27cm 25-26 weeks pregnant The baby is now moving about vigorously and responds to touch and sound. The baby may also begin to follow a pattern for walking and sleeping. At around 26 weeks the baby’s eyelids open for the first time.
Size: about 29cm 27-29 weeks pregnant The baby’s heartbeat can now be heard through a stethoscope. The baby is now covered in a white greasy substance called vernix. It is thought that this may be to protect the baby’s skin as it floats in the amniotic sac.
Size: about 33cm 30-31 weeks pregnant The baby’s is growing plumper, so the skin which was quite wrinkled before, is now smoother. Both the vermix and the lanugo begin to disappear. 32 weeks pregnant The baby baby is now beginning to prepare for birth. He or she will often turn downwards ready for the birth at around this time. 33-40 weeks pregnant Some time before the birth, the head may move down into the pelvis and is said to be ‘engaged’. The average size of a full-term baby is 2.7 to 4.1kgs and 50-53cms long at birth. The placenta is about one-eighth of the baby’s weight, and the umbilical cord is almost as long as the baby.
