Developmental characteristics of eight-month-old infants
1, physical appearance and growth: by this month, the baby can grow 2 ~ 4 teeth.
2. Language development: Children change from early giggling or screaming to recognizable syllables. He would say "mom" or "goodbye" clumsily. When you feel happy, he will find what he said interesting, and soon he will call you in the voice of "mom" or attract your attention. At this stage, he says "mom" every day just to practice speaking vocabulary. He still doesn't understand the meaning of these words and can't really resonate with his parents. With this foundation, it won't be long before children can really call their parents, and eventually they will say it when they want to communicate.
3. Exercise: At this time, the child can sit up without support, sit still, sit alone for a few minutes, play while sitting, turn his upper body around, and don't tip over. Although he still leans forward from time to time, he can almost be supported by his arms. As the trunk muscles gradually strengthen, he will eventually learn how to turn over to the prone position and then return to the upright position. Now he can turn over at will. He will turn over carelessly, from prone position to supine position, or from supine position to prone position. So don't leave the children alone at any time.
At this time, the baby has reached a new development milestone-crawling. At the beginning, there are three stages of baby crawling. Some children climb backwards, some children turn around in the same place, and some climb forward. This is a crawling process. After the baby's limbs are well coordinated, he can stand up, climb on his knees, raise his head and neck, and get his chest and abdomen out of bed. You can crawl around on the bed.
At this time, he may like to listen to the sound of "shua shua" turning pages and tearing paper. Whether he has teeth or not, he will eat cookies and chew.
4. Development of hands and fingers: At this stage, he can basically pinch things with his thumb, forefinger and middle finger very accurately, and he will use this pinching technique for any small object. If you show it to him, he will even snap his fingers. Hand-eyes can coordinate and act together. No matter what you see, you like to reach for it. You can put small things in big boxes, pour them out, put them in and out again and again. In the process of fiddling with objects, gradually improve the perception of things, such as size, length, weight and so on. Children's hands become more flexible, and they will beat the table hard with their hands, which is novel and interesting to the beating sound. They can reach out their fingers and put down or throw away the objects in their hands, instead of passively letting go, even if adults help them pick them up and throw them away. You can play with two objects at the same time, such as putting a small box into a big box, knocking a bell with a small stick, knocking a toy with both hands and so on. Will pinch the toy and give it to the designated person. Open your hands and ask for an adult hug. Grab something to eat with your fingers. Change things from one hand to the other. Whatever you have in your hand, shake it or knock it. At this time, the baby's movements begin to have a purpose, and he will take things with one hand.
5. Cognitive development: At this time, children are curious about everything around them, but their attention is difficult to sustain, and it is easy to switch from one activity to another. Pat, kiss, smile at yourself in the mirror and move your body to get the toys you are interested in. Understand the facial expressions of adults. Adults will smile when praising and show grievances when reprimanding.
6. Emotional and social development: If you talk to your child kindly, he will be very happy; You scold him, and he cries. From this perspective, children at this time have begun to understand the feelings of others. I like being hugged by adults. When an adult stands in front of a child and welcomes him with open hands, the child will smile and extend his hand to show that he wants to hug.
