Your baby is able to hear a lot now, particularly in terms of your body. Did you enjoy a bubbly drink? Your baby can tell. Even plain old digestion is heard. This is why quiet rooms can sometimes be distressing for newborns. Your baby can also see light or dark through the abdomen and uterus. Some babies will turn towards the sun if you are outside. Your baby is about 1 pound and 12 ounces or 794 paper clips. The baby is also about 12.8 inches long, so just a bit longer than a ruler.
