YOUR BABY IS ALMOST AS LONG AS A PEA POD

HOW YOUR BABY'S GROWING

Your baby is the length of  a pea pod about 7.4cm  from head to bottom . He weighs nearly 23g . His head makes up a third of his body length . This  week the part of his brain responsible  for complex thoughts, such as problem solving and memory, starts to form.

Tiny fingerprints unique to your baby are forming  on his fingers although they won't be fully developed until he's about 17 weeks . Now that's  he's  discovered how to suck . he'll be busy practicing his new skills.  He may even be sucking his thumb.

Your baby is beginning to swallow amniotic fluid.  The fluid is mostly  water, but it also contain nutrients  that your baby absorbs, including carbohydrates, protein glucose and electrolytes. Any remaining fluid is turned into  urine by his kidney, which he will be back into  the amniotic fluid.

If your baby's BOY, his testicles have now formed, and his penis is growing, If you're having a GIRL, her ovaries have finished developing and contain about two million eggs.
