The baby is almost fully formed. The bones are beginning
to harden and grow into recognizable arms and legs - with
bendable joints and well-defined fingers and toes.
The genitalia are developing externally. The baby can now
hiccup, though it's too soon for mum to feel it.
In about two weeks, your baby's kidneys will
produce urine which will be released into the amniotic fluid.
The fetus can make facial expressions and may have discovered
thumb-sucking.
In this cube OR sphere you can track the corresponding development progress of week 12.
The baby's size corresponds to the actual size of a child at week 12 (only in an 8cm Sphere or 7cm cube).
