Fingers and Toes are continuing to become longer and more clear of what they are but there is likely to still be some webbing.

Organ Development

The Brain experiencing rapid growth with different brain areas starting to different and lots of neural connections helping to develop more complex brain functions like learning and emotions.   The Pineal Gland is starting to form and produce Melatonin helping in regulating sleep-wake cycles.  Then there are Small Intestines starting to form finger like tiny projections called Villi which help make the small intestines better at absorbing nutrients – these intestines will also be starting to absorb materials known as Meconium and this will be the baby’s first stool after birth.
