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.
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.
