How your baby’s growing:
Your baby weighs about 8 1/2 ounces, and he measures 6 inches, head to bottom — about the size of a large heirloom tomato. His arms and legs are in the right proportions to each other and the rest of his body now. His kidneys continue to make urine, and the hair on his scalp is sprouting. This is a crucial time for sensory development: Your baby’s brain is designating specialized areas for smell, taste, hearing, vision, and touch.
