 Nine to twelve weeks, your baby is going through a really active time of development. The remainder of the fetal organs are being formed. The baby's heart has the four chambers, the kidneys are there, the stomach, the bladder. You'll start to see their fingers form, you'll be able to see their eyes on the ultrasound. The baby will really look like a baby on the ultrasounds the first time you really look at that baby and you can see the entire outline of the structure. You can see development of the brain and the spine and all of the organs. From the twelfth week on, the baby just grows.
