Fertilization (physical)
Before your baby actually starts growing, you set the stage. Last week an increase in the amount of estrogen and progesterone coursing through your bloodstream prompted your uterus to form a lush, blood-rich lining of tissue to support a potential fertilized egg. At the same time, in your ovaries, eggs were ripening in fluid-filled sacs called follicles. -
Germinal Stage (physical)
The germinal stage begins with conception, when the sperm and egg cell unite in one of the two fallopian tubes. The fertilized egg, known as a zygote, then moves toward the uterus, a journey that can take up to a week to complete. Cell division begins approximately 24 to 36 hours after conception. -
Growing Brain, Spinal Cord, Heart, and other organs (physical)
The fifth week of pregnancy, or the third week after conception, marks the beginning of the embryonic period. This is when the baby's brain, spinal cord, heart and other organs begin to form. -
Embryonic Stage (physical)
The mass of cells is now know as and embryo. The beginning of the third week after conception marks the start of the embryonic period, a time when the mass of cells becomes a distinct human being. The embryo begins to divide into three layers each of which will become an important body system. Approximately 22 days after conception, the neural tube forms. This tube will later develop into the central nervous system including the spinal cord and brain. -
Baby Size (physical)
By the end of this week, your baby is likely about the size of the tip of a pen. -
Week 6: The neural tube closes (physical)
Growth is rapid this week. Just four weeks after conception, the neural tube along your baby's back is closing and your baby's heart is pumping blood. Basic facial features will begin to appear, including passageways that will make up the inner ears and arches that will contribute to the jaw. Your baby's body begins to take on a C-shaped curvature. Small buds will soon become arms and legs. -
Week 7: Baby's head develops (physical)
Seven weeks into your pregnancy, or five weeks after conception, your baby's brain and face are rapidly developing. Tiny nostrils become visible, and the eye lenses begin to form. The arm buds that sprouted last week now take on the shape of paddles. By the end of this week, your baby might be a little bigger than the top of a pencil eraser. -
Week 8: Baby's eyes are visible (physical)
Eight weeks into your pregnancy, or six weeks after conception, your baby's arms and legs are growing longer, and fingers have begun to form. The shell-shaped parts of your baby's ears also are forming, and your baby's eyes are visible. The upper lip and nose have formed. The trunk of your baby's body is beginning to straighten. By the end of this week, your baby might be about 1/2 inch (11 to 14 millimeters) long. -
Fetal Stage (physical)
Once cell differentiation is mostly complete, the embryo enters the next stage and becomes known as a fetus. This period of develop begins during the ninth week and lasts until birth. The early body systems and structures established in the embryonic stage continue to develop. The neural tube develops into the brain and spinal cord and neurons form. Sex organs begin to appear during the third month of gestation. The fetus continues to grow in both weight and length, although the majority of the -
Week 9: Baby's toes form (physical)
In the ninth week of pregnancy, or seven weeks after conception, your baby's arms grow, develop bones and bend at the elbows. Toes form, and your baby's eyelids and ears continue developing. By the end of this week, your baby might be about 3/4 inch (20 millimeters) long. -
Week 10: Baby's neck begins to develop (physical)
By the 10th week of pregnancy, or eight weeks after conception, your baby's head has become more round. The neck begins to develop, and your baby's eyelids begin to close to protect his or her developing eyes. -
Week 11: Baby's genitals develop (physical)
At the beginning of the 11th week of pregnancy, or the ninth week after conception, your baby's head still makes up about half of its length. However, your baby's body is about to catch up, growing rapidly in the coming weeks. Your baby is now officially described as a fetus. This week your baby's eyes are widely separated, the eyelids fused and the ears low set. Red blood cells are beginning to form in your baby's liver. By the end of this week, your baby's external genitalia will start develo -
Week 12: Baby's fingernails develop (physical)
Twelve weeks into your pregnancy, or 10 weeks after conception, your baby is developing fingernails. Your baby's face now has a human profile. By now your baby might be about 2 1/2 inches (60 millimeters) long from crown to rump and weigh about 1/2 ounce (14 grams). -
birth
Most women -- about 80 percent -- deliver sometime between 37 and 42 weeks. So where does that leave the other 20 percent? About 11 percent deliver prematurely. Experts aren't sure why some women go into labor early. Possible risk factors include carrying multiples or having an abnormally shaped uterus. -
Laughing (physical)
babies begin to laugh when they are about 12-17 weeks. -
teething (physical)
Teething usually begins around 6 months of age. But it is normal for teething to start at any time between 3 months and 12 months of age. By the time your child is about 3 years old, he or she will have all 20 primary teeth. The lower front teeth usually come in first. -
crawling (physical)
Your baby may start learning to crawl when he/she is between six months and nine months old. By the time he/she is a year old, he/she is likely to be crawling well and exploring her surroundings -
Walking (physical)
Most babies start taking their first steps between 11 and 15 months, but this milestone is hugely variable, and anywhere from 9 to 18 months is really considered normal. Babies are actually born with an innate knowledge of the movements needed to walk; they just lack the physical strength to do it. -
