He may have some hair on his head, including eyebrows and eyelashes. Your baby’s fingernails have grown to the tips of the fingers and he can clench his fists.

The internal organs are maturing. Fat is now being stored beneath your baby’s skin. The blood cells take over for the liver the job of producing blood. Your baby’s gall bladder will become functional, producing bile that is necessary for digestion.

Your baby sleeps and wakes at regular intervals. You will find that your baby is much more active now. He or she turns from side to side and head over heels. Your baby may suck its thumb. Exploring the structures inside your uterus may become baby’s prime entertainment.
