Your Baby: The Beginning Of Braxton Hicks
Your growing fetus weighs in at around 1 pound and measures approximately 10 to 11 in length. Her body is well proportioned, but it still slender, with little fat. She's also sporting new developments from head to toe: her fingernails are almost completely developed; meconium, the baby's first bowel movement, is forming in her intestines; and the lanugo that covers her body is darkening. You're probably feeling a lot of movement and may even notice some early, relatively painless contractions, called Braxton Hicks. Don't worry -- these contractions don't mean you're going into labor, and your baby is unaffected by them.
- Proportions of the body are now quite similar to a newborn although thinner since she hasn't begun to form body fat.
- Bones located in the middle ear harden.
- Your baby is able to hear. (Dad, did you know? Low-frequency sounds mimicking a male voice penetrate the abdomen and uterine wall better than the higher frequencies of the female voice?)
- The eyes are formed, though the iris still lacks pigmentation.
- The pancreas, essential in the production of hormones, is developing steadily. She has begun producing insulin, important for the breakdown of sugars.
- If born now, your baby has a 15% chance of survival, her odds going up with each passing day. .
- The average baby at this stage weighs 1.1 pound (501gm) and is 11.38 inches (28.9cm) long.
