Your Baby's Development
By now, your baby has developed enough coordination to grasp with the fingers. If shown a bright light, your baby may turn toward it in your uterus.
He or she continues to gain weight — developing fat at the rate of half an ounce (14 grams) a day. In general, boys weigh more than girls at birth.
After this week, you may lose the mucous plug that sealed off your uterus from infection. The mucous plug can be lost a few weeks, days, or hours before labor and is thick, yellowish, and may be tinged with blood (the mucous plug is also called bloody show). As the cervix dilates in preparation for the labor, the plug is discharged from the body. Be sure to speak with your health care provider about any discharge you may be having.
