Being pregnant in the summer may be no fun for moms to be, but there may be an advantage for babies. A British study finds children born in late summer or early autumn are often taller and stronger. That may have to do with the mother's exposure to the sun.

The body makes vitamin D from sunlight and this vitamin is crucial for bone building.

Research from Bristol University suggests this process may even occur while the fetus is still in the womb.

Another study is trying to determine whether giving vitamin D supplements to pregnant women increases the bone density of their babies at birth and in childhood.
