Baby parts development summary

The muscular frame gets stronger with the increase in physical activity at 6 months. The skeleton is growing and requires tremendous support for the development of bipedalism. The baby gradually rises from the surface higher and higher.

There are serious functional changes in the work of internal organs. Body growth implies an increase in internal organs. There may be malfunctions in the functioning of the digestive tract with a strong growth spurt, as they do not have time to adjust to this pace.

There are some changes in the composition of the blood and the specifics of the work of the hematopoietic organs. The work of the heart changes and the pulse rate decreases.

Muscular frameThe muscles of the trunk are getting stronger by 6 months. The back becomes stronger. This allows the baby to start crawling on their stomach. Training the arms and abdominal muscles contributes to quick sitting. Children can voluntarily tense their muscles.

Skeleton – The intensive growth of the skeleton far outstrips the growth of muscle mass, but the bones remain slightly pliable and weak. The final strengthening of the skeleton will come after 1 year. A large fontanel is slightly overgrown in the skull.

Teeth – The first tooth may appear outward at 6 months. The lower incisors are cut. These are milk teeth under which the molars already lie. The appearance of the first tooth can be painful for the baby.

Digestive systemThe length of the esophagus is now about 12 cm. It is funnel-shaped. The muscular sphincter of the inlet group of the stomach is still poorly developed. This leads to frequent regurgitation. The intestine is long and chaotically folded.

Excretory systemThe kidneys are still completely immature both morphologically and functionally. The filtering surface increases and the tubules lengthen. Stable parameters of water-salt homeostasis are maintained. The number of urination is slightly reduced.

Circulatory system and heartOvergrows the oval hole between the atria. It occurs in 60–80% of babies at 6 months of age. There is a separation of arterial and venous blood flow. The high regenerative capacity of the myocardium. The blood supply to the heart muscle is good.

Your Baby Growth at 6 month

The visual and auditory orienting reactions of the baby are greatly aggravated by 6 months. He actively uses his sense organs for development and cognitive activity. The kid shows progress in intellectual development and psycho-emotional improvement.

Achievements in physical activity are due to the strengthening of the muscles of the body. The child does difficult work on the way to the vertical position of the body.

“Six months is an important and very interesting milestone in the postnatal development of a child that requires special attention from parents.”

The introduction of complementary foods is mandatory at 6 months. Skeletal growth requires additional nutrition. A nutritional complex rich in vitamin D is useful. You can add this vitamin separately. The 3rd dose of DTap and PCV13 should be given at 6 months of age. Closely monitor the baby’s temperature, skin rashes, and stool regularity after the introduction of complementary foods.

Sleeping Schedules at 6 Month

Sleep regression often manifests itself within six months. This is a persistent violation in the schedule due to a sharp jump in growth and development. The adaptation period takes from 2 to 4 weeks. It is necessary to adapt to the change in the regimen of the child during this period without forcing him to sleep by force.
