Congratulations on becoming pregnant! We are sure you are curious about how your pregnancy will progress, and how your baby will develop week to week over the next few months. Here we will discuss how a baby develops through the first, second, and third trimesters. Particularly starting from a tiny cluster of cells to a full-grown baby. Feel the glimpse of your baby’s movement and development inside your uterus. Similarly, feel the changes of physical and emotional going on through. Also, see how life is growing inside you coupled with the progress of every stage.
Step one of conception is when the sperm penetrates the egg to complete the genetic make-up of a human fetus. At this moment (conception), the sex and genetic make-up of the fetus begins. About three days later, the fertilized egg cell divides rapidly and then passes through the Fallopian tube into the uterus, where it attaches to the uterine wall. The attachment site provides nourishment to the rapidly developing fetus and becomes the placenta.
Baby’s development at one-month pregnancy
After 4 weeks or one month, the baby has changed from clusters of cells to an embryo and divided into two layers. Generally. the basic structures of the embryo have begun to develop into separate areas that will form the head, chest, abdomen, and the organs contained within them. Small buds on the surface will become arms and legs. A home pregnancy test should be positive at this stage of development (most tests claim positive results one week after a missed period).
Baby’s development at two months of Pregnancy
Generally, at 8 weeks or two months, the fetus is about a half-inch long (1.1cm) the size of a kidney bean. Facial features such as developing ears, eyelids, and nose tips are present. The limb buds are now clearly arms and legs, while the fingers and toes are still developing. Baby’s fingers are clear In brief it slightly looks like a web.
Baby’s development at three months of pregnancy
At 12 weeks or three months, the fetus has grown to about 2 inches (4.4cm) in length approximately 23 grams. The baby may begin to move by itself. The fingers and toes are discernible, and the fetal heartbeat may be audible by Doppler ultrasound. Therefore Ultrasound techniques can detect sex organs by now.
Baby’s development at four months of pregnancy
At 16 weeks or four months, the fetus is about 4 and one-half inches long and weighs 140 grams. Now baby resembles an infant; the eyes blink, the heartbeat is easier to locate. Facial features (nose, mouth, chin and ears) are distinct, and the fingers and toes are clearly developed. The skin on the fingers and toes even has distinct patterns (fingerprints!). Women should be able to feel the uterus at about 3 inches (6.6 cm) below the belly button; this is the beginning of the “baby bump” (abdominal swelling due to an expanding uterus) in some women.
Baby’s development of five months of pregnancy
At 20 weeks or five months, the developing fetus is about 6 inches long (13.2 cm) and may weigh about 10 ounces. Babies eyelids, eyebrows are formed in the fifth month. You can see babies legs upright The baby may begin to make movements that the mother can feel at about 19 to 21 weeks; this baby movement is termed “quickening”. The baby at this stage of development can move its facial muscles, yawn, and suck its thumb. The expanding uterus at 20 weeks is at the level of the belly button.
Baby’s development at six months
At 24 weeks or six months, the baby may weigh 1.4 pounds and can respond to sounds. Doppler studies show the sound response by measuring movement and heartbeat rates. Sometimes the baby will develop hiccups that the mother can feel! The baby’s inner ear canals are developed at 24 weeks, so researchers consider the fetus can sense its position in the uterus. Now your baby’s skin has become smooth as a result of fat development has started.
Baby’s development seven months
At 28 weeks or seven months, the baby normally weighs about 2 and one-half pounds. Now baby can open and close his eyelids. At this stage development of the baby is so much that if the baby takes birth prematurely for any reason can survive. The chances are good that the infant will survive but usually would require a hospital stay. Your doctor may discuss signs of premature labour and suggest you (and your partner) take classes on what to do at the time of delivery of your full-term baby
Eight months of pregnancy
At 32 weeks or eight months, many babies weigh about 4 pounds and have movements that the mother can feel. A layer of fat coupled with Lungs have been developed. Thus baby looks chubby Your doctor may ask you to make notes about the baby’s movements and discuss breastfeeding and other options along with scheduling visits every two weeks until you deliver the baby. Some women begin to leak a yellowish fluid from their breasts around this time; this is normal. This fluid is known as colostrum, and its presence indicates the breasts are primed to start producing milk for the newborn baby.
Nine months of pregnancy
So, finally, Baby’s delivery date has almost arrived. At 36 weeks or the ninth month, the baby is about ready to take birth and has reached an average length of 18.5 inches from head to heel length and weighs about 6 pounds. However, a baby’s weight and length are quite variable and are influenced by the baby’s genetics, the baby’s sex, and many other factors. During this time, the baby has begun to rotate itself into the delivery position of head first into the pelvis. All the organs are fully developed which allows them to survive and continue their growth outside the uterus.
