Week 6
Your baby is still very tiny … only about the size of a kidney bean. But this is a big week as organs and parts of the body begin to take shape.

Week 10
This week your baby's brain will experience enormous growth. The rest of her body is growing too; she's now about the size of a small plum and weighs about half an ounce.

week 12
Your baby continues to grow and is now about 3 inches long. By Week 12 your baby has a profile, complete with a little chin and a tiny nose. Inside the mouth folded tissues join to form the palate, or roof of the mouth, which separates the oral and nasal cavities.

week 16
Overall growth continues, and your baby now weighs about 2.8 to 3 ounces and is about 4 or 5 inches long. You're not the only one who's smiling! Your baby can now make facial expressions because of the development of her facial muscles. This week she can squint, smile and frown. This is probably not an indication of mood but may be linked to random impulses in the developing brain.http://www.gerber.com/Public/Default.aspx -
Week 19
Welcome to the fifth month of pregnancy! This week your baby will grow to about 5 or 6 inches and will weigh about 7 ounces by week's end. Your baby is working on protecting her skin as she develops a waxy substance called vernix caseosa, which will disappear at birth. Secreted by the glands in the skin this week, vernix caseosa protects the growing skin from becoming chapped or wrinkled from floating in amniotic fluid.

Week 24
Your baby still has a lot of growing to do. At 1.2 pounds and 8 to 9 inches long, she should add at least another 5 pounds before birth for optimum health.This week she prepares herself for a big cry upon arrival. Her lungs begin to produce surfactant, a wetting agent that will help her breathe correctly and keep her tiny lungs from collapsing or sticking together.

Week 28
At about 2 pounds 4 ounces and 13.8 inches from head to toe, your baby has certainly come a long way! This week marks an important milestone for your baby's brain development. Until now the surface of your baby's developing brain was smooth. During this week, her brain begins to form its characteristic grooves and indentations, allowing the brain's surface to expand while it develops within your baby's tiny skull. http://www.gerber.com/Public/Default.aspx -
Week 32
Your baby is now about 4 pounds—an incredible increase of almost 2 pounds from last month—and about 15.5 inches long. Your baby's appearance changes rapidly this week. Most of the wrinkles disappear from her face, and there may be a lot of hair on her head. In fact as the lanugo hair on her body begins to fall off, the hair on her head grows even faster. By week 32 some babies already have a thick head of hair while others have only a few strands.

Week 36
Your baby now weighs a 6 pounds and is 20.7 inches long. Your baby works hard to accumulate all the fat she can in preparation for delivery. Her body grows rounder every day, since about 15 percent of her total weight is now made up of fat. Once she's born, this fat layer will help her maintain her body temperature and give her a reliable energy source.

Week 40
The average birth weight for babies at 40 weeks is about 7 pounds, and the average length is about 21 inches.There are a number of surprising physical characteristics you may notice upon your little one's arrival. You may not have realized the extent to which your hormones can affect your baby at this stage. Because of the presence of your hormones in your baby's system, your baby's genitals (scrotum in boys and labia in girls) may appear enlarged. http://www.gerber.com/Public/Default.aspx
