At 30 weeks a baby grows about 15.7 inches long and her weight is around 3 pounds (could be compare with a size of a large cabbage). At this stage of the development an amount of amniotic fluid is about 1.5 liters or a pint and a half. A baby still develops the eyesight and her eyes are opening; however, the baby only has 20/400 a vision ratio as to a comparison of 20/20 of perfect adult vision. In other words, a baby only recognizes objects that are a few inches to her face. Most recognizable facts of fetal development at this stage: baby's toenails by now are formed. A baby starts practicing to breath, and also continues to gain weight.
