The fat your baby is storing is filling out his body proportionally, making him look more like the newborn you’ll have in your arms in a few weeks.

Your baby’s senses are developing progressively. At this time the ears are fully functioning, and he can hear the sounds coming from the outside world, especially low pitched sounds. His fingers are grabbing at whatever they find, like the umbilical cord or his other little fist, and he has fully developed finger tips. His sense of taste has started to surface with the development of taste buds on his tongue which has also just developed.

The weight increase is noticeable these weeks because in a few days it has increased over 100 grams, which for such a small baby is a considerable amount. Now he weighs over half a kilogram and almost a pound and a half. And he measures almost 12 inches or 30 centimeters.
