Your Baby's Development
The senses your baby will use to learn about the
world are developing daily.
Taste buds have started to form on the tongue, and
the brain and nerve endings are formed enough so that the fetus can feel touch. Your
baby may experiment with this newfound sense by stroking his or her face or sucking
on a thumb, as well as feeling other body parts
and seeing how they move.
Your baby's reproductive system continues to develop. In boys, the testes have
begun to descend from the abdomen, and in girls, the uterus and ovaries are in place
and the vagina is developed.

Your Body
If you haven't felt them already, you may soon notice your uterus
practicing for delivery with irregular, painless contractions called Braxton Hicks
contractions. You may feel a squeezing sensation in your abdomen. Don't worry, though:
Your baby may be able to feel the contraction as it squeezes the uterus, but these
aren't dangerous or harmful.
But if the contractions become more intense, painful, or frequent, contact your
health care provider immediately because painful, regular contractions may be a sign
of preterm labor.
