During the seventh week most of the growth occurs in your baby’s head as your little genius develops new brain cells, which are generated at the rate of 100 per minute.
Their limb buds are now fully formed arms and legs, and the focus is now on the joints such as the elbow and knee. Soon your little one will start having fun, bending and flexing and will realise his or her strength (and you’ll realise it too!) Nostrils, lips and a tongue also begin to form, along with little teeth under your baby’s gums. Also important this week is the development of your baby’s kidneys.
