Baby development

The groundwork for my permanent teeth begins to emerge.

My legs and arms have got the right proportions in relation to my body whilst my kidneys have begun producing urine. In the brain, several millions of nerve cells, which will oversee my ability to move by connecting my brain to my muscles, spring into action. This allows me to make conscious movements such as sucking my thumb of my own free will, an act that my mother should be able to see with ultrasound or an image of me rocking back and forth in her belly.
