12 Weeks PregnantAt 12 weeks pregnant your baby will already look like a tiny human being! It is about 6cm long and weighs about 15g. To give you an idea of how little that is, if you took 4 level teaspoons of peanut butter and put them on the scales, that would be about 15g! But your tiny little fetus now has arms and legs, with visible fingers and toes, and now has increasingly well defined facial features.The baby’s body at 12 weeks pregnant is now straighter and the first bone tissue has begun to appear. The face is now formed, with a chin, high forehead and small button nose.The eyes are developed and although they are shut tight with sealed eyelids, they now show reflexive movements, a bit like those movements we have when in deep (REM) sleep. The ears are visible but are still small in proportion to how big they will be by the time the baby is ready to be born.We now know that from 3 months pregnant the tiny brain is already forming neural pathways,

Which suggests that stimuli such as vibrations, the mother’s heartbeat and perhaps even external noises may begin to be registered by your baby. The fetus is also starting to squirm around, although you can’t feel it yet because there is still a high proportion of amniotic fluid all around it which cushions both of you.The arms and legs can move freely and if you have a scan (see video clip example below) at 12 weeks pregnant you may actually see them moving, even the arms waving about, which is really exciting! The skin is still permeable to amniotic fluid. The nails on the fingers and toes are starting to grow and if the palm is touched, the fingers will curl. At around about 12 weeks pregnant the placenta has achieved its final shape and takes over from the yolk sac to become the baby’s life support system, supplying it with the nutrients it needs to keep on growing.

The placenta is much larger than the baby at this stage. After its initial rapid enlargement the placenta then slows to a much slower but steady growth rate and by the time the baby is born it will weigh about one sixth of the baby’s weight.Below is a 12 week ultrasound photograph showing the positions of the head, hand and leg.
