Baby Stages

Know and understand the development of the baby within the womb on a weekly basis. Here are the details of information on how the baby grows and develops from week one to week thirty six.

(Weeks 1 to 12) First Trimester.
A healthy sperm will fertilize into a healthy egg.  The egg  then moves to the uterine area and implants on to the wall. This is the implantation stage. A primitive neural tube forms, which eventually converts to the nervous system. Next, forms the  primitive circulatory system and a tiny heart. This combination  provides a solid foundation, on which the entire life will be supported and nourished.

During the Fifth week, a beating heart is formed whose murmurs can be heard with the help of a stethoscope. An umbilical cord is also formed, to provide fresh blood, oxygen and food to the young fetus. The rudimentary heart functions on its own, by pumping blood through its primitive circulatory system. Along with the growth of lungs, important organs like hands, feet and arms also start developing,

During the sixth week, the limbs grow at a fast rate, to create a strange sensation in the womb. Brain cells also multiply. Eyes and a pair eye buds are formed at the edge of the head. Internal digestive organs like pancreas, stomach, intestine and liver appear at this time.

During the seventh week, tiny little feet and hands come out of the body with a well formed elbow to support the hands. A pair of legs will support hose tiny feet as well. At this time, a thin, gum line is also formed in the mouth.

By week eight, cartilages and bones occupy their place in the body. Eyes and digestive systems are evolved. The baby starts moving both in sideways, as well as upside down. The fingers also start showing distinctly formed finger prints and the fingers will also have trough shaped ends, where the future nails will grow.

By week ten, the tiny tot becomes a fetus with advanced organ systems in her body. Eyes are still shut down, but the cornea and iris will start forming with in the shut eye lids,

The placenta will start working during this time, to transport fresh food and oxygen to feed the baby.
By week eleven, hairs and nails start to grow and develop,

Kidneys also start functioning. The genital organs will also develop and take the set gender characters. Ears shift to the sides of the head, while the eyes also begin to move close to each other. Very tiny vocal chords begin to take shape.

(Weeks 13 to 24) Second Trimester.
Week thirteen is a growing month. All organs get their final shape and morphology and the heart is getting rhythmic. The neck becomes longer and stiffer. Placenta is busy in nourishing the tender baby.

By fourteenth week, thyroid and other hormone secreting glands produce minute quantities of hormones. The skin is  transparent and thin fine hairs (lanugo) starts appearing on the body. Bones will get stronger and Muscle and brain coordination begins. 20 milky white teeth buds are developed. Rapid skeletal movement is observed. Fetus gains more weight and becomes mature.

(Weeks 27 to birth) Third Trimester.
Heartbeat is stronger and can be heard by a stethoscope. 

Eyelids starts to open very slowly and clear eyes are easily visible. There is a pattern in sleep and wakefulness. Lungs are ready for breathing. Taste buds are formed and nourishment is stepped by the placenta.,

By the end of twenty sixth week, eyes, eye lashes and brows are completely formed. Brain grows with strong sensory feelings.

Skin gets clear now with wrinkles free. The fetus looks like a baby, as the head looks quite proportional to the body. Eyes are very sensitive to the light, while the finger and toe nails reach their full length. Each cartilage is soft and well formed. Entire body system is completely functional. The head gets firmer day by day, and the whole body is sustained by a regular  supply of food. The baby moves almost regularly by kicking and moving. It puts on more weight during this time. The baby also takes a head down position to facilitate an easy delivery. But, the scalp region is still underdeveloped to accommodate the body through the narrow birth channel.
