From the time a child is born, he has the ability to observe this new world, and when he comes to this new world, he grows up like a sapling, step by step. Every parent wants their baby to be healthy and smart, and this is also the good wish of our medical workers. Children are the future of the motherland, and “a strong youth is a strong nation”, and this effort is to start from the newborn, so we should be committed to the early development of infants and young children to promote, this promotion is never blindly “pulling up the seedlings to help grow”, but in accordance with the normal development of the baby On the basis of the normal developmental pattern, we provide a rich environment for babies, and give them a variety of benign stimuli to help them develop better. Today we will talk about the developmental performance of 7-8 months old babies: a, large movement 7, 8 months old baby sitting more stable, he is not satisfied with just stay in a fixed position to play, he began to take the initiative to explore the outside world, to approach his interest in people and things, at this time, he began to learn to crawl. When he first learns to crawl, his abdomen cannot leave the bed, which is what we call belly crawl, and his upper and lower limbs are not coordinated, so he will turn in circles or move backwards when crawling, and slowly learn to leave the bed with his abdomen and crawl forward with his arms and knees. This is what we call hand-knee crawling or four-point crawling. Crawling is an important stage in the development of infant movement, but also a good whole body movement, crawling when the whole body parts are involved in activities, both to vent off the baby’s excess energy, but also to exercise muscle strength, to promote the development of cerebellar balance function, to prepare the baby to stand and walk. So mothers and fathers must create a good, safe little world for the baby to crawl, to encourage and develop the baby’s crawling activities, it is best to circle a place on the ground and lay a mat, which will be safer. Some crawl in bed for fear of falling down. The mat can be laid on the floor next to the sofa, you can also practice holding station, because at this time, some babies can already hold the sofa to stand for a while. Second, fine motor 7, 8 months baby’s hand movements are more flexible, can pinch some small objects, such as small buns, small tomatoes, small soy beans or something, the thumb began to separate, you can use the thumb and other four fingers to separate the pinch. And they start to play with toys purposefully, not just knocking and beating them unconsciously. For example, you can use your fingers to fiddle with toys, turn toys upside down, and knock two toys against each other. At this time, mothers and fathers can prepare some finger paddle toys, small blocks, knocking toys, toys with music that can be pressed, toys that can be plucked and inserted, etc. to develop the baby’s two-hand cooperation, hand fine manipulation and hand-eye coordination and association ability. Language and cognition 7 and 8 months old babies can start to make some simple syllables such as “fight”, “mom” and “dad”, but these are unconscious pronunciations. However, parents can take the opportunity to tell their babies that I am “daddy” and I am “mommy” every time they make the “daddy, mommy” sound. This will help your baby to gradually associate the unconscious sounds with real people or things. At this age, babies also like to observe people’s activities and begin to imitate some simple sounds and actions. For example, when an adult coughs, he also imitates coughing, and when an adult claps his hands, he also imitates clapping. This is also a good time to teach your baby to establish a connection between language and action, and when your baby imitates doing actions, you can tell her what she is doing. At 7 and 8 months, babies also look for hidden objects, can distinguish between acquaintances and strangers, and can recognize and respond to different attitudes, expressions, and sounds of adults. In addition, their interest in the surrounding environment has also increased, and they can look at more objects around them, and will focus their attention on things and toys that interest her, some like to look at cars in the street, and some look at birds in the sky, so once this month-old baby goes outside, he keeps looking at things that interest him, and when he focuses on them, he even ignores the family’s calls. Often parents say, my baby interacts well at home, once outside they stay, only know to look around, and do not interact with us, in fact, the baby is looking at the outside world.
