Your baby will be growing rapidly over the next 9 weeks from roughly 2 inches (5 cm) to 8 inches (20 cm). With this rapid growth, the blood vessels in the placenta are increasing in size and volume to provide the baby with more nutrients. Some of your baby’s organs are almost complete including the pancreas, the thyroid and gall bladder.
Your baby’s head is also developing. Its ears are moving toward their final position on the sides of the head. At this stage, the head accounts for about half of its body length. The baby’s eyes are still very wide apart and the eyelids begin to fuse close temporarily. This week, the irises, the colored part of your eyes, are also developing.vYour baby will also begin to grow teeth, fingernails, toenails and hair follicles.
