Babies entering 6 months of age begin to slow down, especially when it is noticeable that previously gained weight rapidly now shows a tendency to grow slowly. Although the baby's physical growth is not obvious, the baby's intelligence level improves rapidly, which is also one of the more obvious characteristics of the 6-month-old baby throughout the development process.
1. The level of physical development of the baby
Although the baby's physical development shows a slowing trend during this period, it is still growing steadily overall.
height
Babies this month have an average height of 2.0 cm.
Exercise has a great role in promoting the growth of your baby's height. Outdoor activities not only promote the intelligent development of the baby, but also allow the baby to bathe in the sun, promote calcium absorption, and make the bones strong.
weight
Babies this month can gain 450 to 750 grams of weight. Babies with a large amount of food and good appetite may gain more weight than last month. If the daily weight gain exceeds 30 grams, or the weight gain exceeds 300 grams in 10 days, the amount of milk fed should be appropriately reduced.
Head circumference
In infants this month, the head circumference can grow by 1.0 cm. The growth of the head circumference is difficult to see from the appearance, the increase in the value is not large, if you can not grasp the correct measurement method when measuring, it is best to ask a doctor to measure, so as not to bring unnecessary trouble to parents due to measurement errors. The size of the head circumference is not the same for all babies, and there are individual differences.
fontanelle
In infants this month, the anterior fontanelle has not been closed, and the anterior fontanelle ranges from 0.5 to 1.5 cm. Regarding the anterior fontanelle, Mom and Dad are most worried that the premature closure of the anterior fontanelle will not affect brain development. If the front fontanelle is indeed closed prematurely, the mother's concern is also justified, but most of the time it is an illusion caused by the baby's small front fontanelle. A small fontanelle does not equal closure; The front fontanelle is small, and it cannot be proved that it will close early. Some babies are born with a small fontanelle, and during the entire development process, the anterior fontanelle does not change much, and most of them begin to gradually close after the age of 1. If it is a disease such as microcephaly, narrow cranial disease or osteopetrosis, in addition to small fontanelles and early closure, there will also be small head circumference, bone suture closure, overlap, and backward intellectual development. To dynamically observe the anterior fontanelle, the absolute value of a measurement does not explain the problem, and whether the measurement method is correct should also be considered.
2. Baby's motor development level
In big movements, the head rotates freely. When lying prone, the legs are raised and extended quite high, and can be flipped and turned in all directions, and can be turned from supine to prone. You can use your hands and knees to support your body and stretch your limbs to make your body jump forward or backward. Creeping on a stomach against the ground, supporting the climb forward or backward. Someone needs support to stand. With a little support, you can sit, balance well, and lean forward or on both sides. When sitting in a chair, you can grasp shaky objects. Can jump up and down, can sit alone for a short time, can sit alone for half an hour without support, but must lean forward with both hands to maintain. When turning over from prone, you can bend sideways to a half-sitting position.
In fine movements, you can hold the bottle, and at the same time, you can turn your wrist to hold the object in your hand, and you can also reach the object with one arm.
3. Baby's language development level
This month's baby, still can not speak, but the perception of speech is clearer, pronunciation becomes active, will unconsciously make some unclear voice, will unconsciously call "mama", "baba", "dada".
Today's baby, as long as he is not sleeping, his mouth is constantly "talking", although parents can't understand what the baby is saying, they can still feel the meaning of the baby. For example, the baby will fiddle with the toy in his hand while making sounds such as "click", "click", "da", "mom" and so on, as if he is talking to himself. If parents play with the baby with the small cloth bear, the baby will clap his small hands and shout "Oh" and "Oh" in his mouth, showing great interest in the little cloth bear. If the mother claps her hands to call the baby's name, the baby will also open her small hands and shout "ah" and "oh" in her mouth, as if in response to the mother. When dad asks baby, "Where's Mommy?" When the baby looks at the mother, his face shows a look of joy. Sometimes, the baby also pouts his small mouth and bubbles pop out of his mouth. All this shows that the baby's language ability has been greatly improved.
4. The baby's sensory development level
Babies aged 6 months already have a sharp hearing and have the ability to remember the sounds they hear, can hear the voices of parents and caregivers, and will turn to them when they hear these sounds. For example, when the lights are turned off at night, when the baby is crying, the mother and the baby talk or hum a lullaby, even if the baby can't see the mother, there is no physical contact with the mother, and the crying will stop. If a stranger speaks, it will not make the baby stop crying, and may cry more severely.
5. Baby's emotional response level
Today's baby will laugh when he is happy, cry when he is frightened or in a bad mood, and his mood changes very quickly, and he has just cried extremely devotedly, and in the blink of an eye, he laughs uncontrollably. When the mother leaves, the baby's small mouth flattens and flattens as if he wants to cry, or cry. If the toy in your baby's hand is taken away, he will cry in horror, as if he has been hurt. When the baby hears the mother's gentle and kind words, he will open his small mouth and giggle, and gather his small hands together in front of his chest as if clapping his hands. If the mother shouts the baby's name in a place where the baby can't see, the baby will look around for the source of the sound, and smile happily when he finds it.
7. The level of mental development of the baby
When the baby is 6 months old, he has his own observation and understanding of the things around him, and it seems that he will also look at the faces of adults. The baby can also smile at the kind smile and words of outsiders, and when he sees a serious expression, he will be uneasy in his mother's arms and dare not look. Hearing someone mention his or her name in a conversation, you turn your head to the interlocutor. When the mother slaps her hands together and reaches out to the baby, the baby knows that the mother wants to hold him or her, and she opens her arms happily. When the mother picks up the bottle and shakes it toward the baby, the baby knows that the mother is going to feed, so she can't wait to open her small mouth. Sometimes the mother pretends to be scolding, and the baby's expression will change greatly or even be uneasy or crying. Babies can also understand some words that are often used repeatedly, such as "mom", "dad", "suckle" and "go to bed".
