BABY DEVELOPMENT STAGES INFO

I think it is very important to have knowledge about baby development stages. I enjoy spending a great deal of my own time researching all areas of health. This section on pregnancy is fulfilling for me because of all the up to date information that’s readily available. It’s just fascinating to me how we all start off as a combination of a sperm and an egg that come together. Furthermore, how from that union certain cells join and form specialized organs and complex systems. This section is also great for moms who are curious about the stages in their baby’s life. What are the amazing stages in each of our lives?

STAGE 1 Day 1 thru 14

There are roughly 200,000,000 sperm that ungulate towards a female egg during conception. Incredibly enough only one sperm succeeds at fertilizing the egg. At the moment of conception all the features of that person are set. Next, the first cell divides in two and each of the new cells divide again and again as they travel to a protected area of the womb. Close to the end of the second week the mother’s menstrual period is suppressed due to the secretion of the hormone (hCG). This is the initial point at the baby development stages and remains integral to the proper growth of the little one.

STAGE 2Day 17 thru 21

The individual’s blood vessels start to form. Also, the future sex cells that will give rise either sperm or eggs start to group together. The foundations of the spinal cord, nervous system, and brain are laid out. Around day 21, the little heart begins to beat, building in strength everyday. The heart beats an astounding 70 beats per minute at first, then reaches a maximum of 170-191 beats per minute at seven weeks. The eyes begin to develop and the ears are now present. The baby development stages are an integral part of the manifestation of a newborn.

STAGE 3Day 26 thru 36

The lungs now begin to take shape. Two little arms start to protrude and budding legs follow. The nose starts to develop and the mouth takes shape. The thyroid gland begins to grow. Blood starts to surge through the baby’s veins and the tongue now begins to form. The baby devlopment stages that occur at this point are important for establishing blood flow through the blood vessels. The baby’s face now shows itself. Around day 36, the baby’s eyes develop their first color in the retina.

STAGE 4Day 40 thru 52

The baby development stages are in full swing by now. The baby now makes its first reflex movements. Next, the fingers begin to form and then the toes just a few days later. Around day 42 nerve connections form that lead to a sense of smell and the baby’s brain divides into 3 parts ( one for hearing, one for seeing and the other for understanding language and experiencing emotion ). Next, the joints begin to form and mom skips her second period. Facial muscles develop along with the budding of milk teeth. Eyelids start to show and start protecting the developing eyes. Internal organs are visible, but still immature. Electrical activity is present in the brain and almost 100% of muscles are present, each with its own nerve supply. The baby development stages at this point is critical so the baby's brain divides successfully.

Around day 52 the baby starts spontaneous movements of hiccupping, squinting, furrowing the brow, head turning, touching the face, breathing ( without air ), opening the mouth, yawning, moving individual arms, frowning and sucking.

STAGE 68 Weeks thru 11 weeks

Around week 8 the baby is about the size of a thumb and well proportioned. The heart has a steady beat, the kidneys function and the liver is producing blood. The knees elbows and the skull are forming. Close to 4500 structures are present and the skeleton of the legs, arms and spine begins to stiffen as bone cells are added. Close to the 9th week if prompted the baby’s hands and eyelids close. The thyroid gland switches on and there’s early muscular movement. The genitalia that started forming around the 7th week are now visible, which indicates whether it’s a girl or boy ( a doctor won’t be able to be accurate with the baby’s sex until the 12th to 20th week. The baby development stages are critical here for correct forming of a baby’s genitalia.

By week 10, the fingernails begin to develop and the fingerprints begin their 7 weeklong formation. The eyelids also fuse together until about week 8, whereby protecting the delicate eyes. The number of connections between muscles and nerves has more than tripled since the week before. During week 11, the baby practices it’s breathing and is able to urinate. The vocal chords and taste buds form and the stomach muscles can now contract. The baby can make complex facial expressions and even smile. The baby development stages at this point in time are complex and require pin-point timing of connections.

STAGE 7Week 12 thru 15

Week 12 the baby can swallow and responds to skin stimulation. Also, fine hair begins to grow on the upper lip, eyebrows and chin. Around week 13, the baby is active and may have facial expressions that may resemble the parents. During week 15 a wild production of nerve cells begins and will continue for a month. At this point, the baby development stages are critical for the correct number of nerve cells. The second surge of nerve cell growth occurs around week 25.

STAGE 8Month 4 thru 6

Month 4 the baby may suck its thumb, turn somersaults, has a firm grip and its nostrils and toenails become visible. Also, the ovaries of girls contain the beginnings of eggs. The baby starts to develop sleeping habits. Around 4 and half months the baby is able to experience discomfort or pain. At 5 months, each side of the brain has a billion nerve cells and the testes descend in boys. If you’re a mom you may feel the baby kick, turn or even hiccup. Around 6 months, the baby sleeps, and then wakes up with a possible stretch afterwards, and will possibly be able to hear by the next week.

STAGE 9Month 7 Thru 9.5

During month 7, the eyelids begin to reopen, which prepares the baby for seeing the world. The baby development stages are almost complete inside of the mother. The eyelashes have now become well developed. Next, during week 8 the pupils of the eye respond to light and the skin becomes pink and smooth. The Childs fingernails reach to the tip of the finger and the baby is really getting cramped now. At 9.5 months the child is ready to come out and triggers labor then birth occurs.
