sports

At this time, the baby can stand alone for a while, can crawl quickly, and adults will walk hand in hand; Children of this age are also in the transition period of walking upright. Once a child can sit alone, he no longer sits honestly and wants to stand up. At first, I would stand there holding something, and my legs only supported most of my body weight. If the child is well developed in sports, he will still move his feet with something or stand by himself, and there is no need to hold something. Children can get up from their beds or seats by pulling the railings, holding their mothers with their hands or staggering with something. Some children learned to squat down and pick up things with one hand during this time.

Physical skill development

As children learn to open their fingers at will, they will begin to like throwing things. If you put a small toy on the tray or bed of his chair, he will throw it down and ask someone to help him pick it up so that he can throw it again. If you roll a big ball for your child, at first he just pats it casually, and then he will pat it and let the ball roll in your direction.

Language development

At this time, the baby may have called mom and dad, and can take the initiative to express the language with actions; The age at which children pronounce recognizable words varies greatly. Some children have learned two or three words when they are one year old, but it is more likely that the language of a one-year-old child is some fast and unclear sounds, with sounds and changes, which can recognize the language. As long as the tone, intensity and nature of the child's voice change, he is preparing for speaking. When he speaks, the stronger your reaction, the more you can stimulate your child to communicate in language. Began to imitate other people's voices and ask adults to respond, and entered the embryonic stage of speaking. Under the guidance of adults' language and actions, you can imitate clapping, waving goodbye and shaking your head.

visual development

This month's baby will start to look at the images in the mirror. Some babies can realize their existence by looking at themselves in the mirror and smiling at themselves in the mirror. Eyes have the ability to observe different shapes and structures of objects, and become a favorable tool for babies to know things, observe things and guide sports.

Babies can know objects by looking at pictures, and like to look at people and animals in picture books.

The baby has learned to look at the face and color, especially the expressions of parents and caregivers, and has a more accurate grasp. If the mother smiles, the baby knows that the mother is happy and recognizes what he has done, which is an appreciation for him. He can do it. If the mother looks angry, the baby knows that the mother is unhappy and blames him. He can't do this. Parents can use this ability of babies to teach them what to do and what not to do. But at this time, the baby does not have the ability to distinguish right from wrong, and can't tell the truth to the baby, otherwise it will make the baby feel at a loss.

If the baby hits the mother's face, the mother should never smile at the baby, but should show a serious expression and tell the baby that it is not good to hit the mother and it is wrong to hit people. Although simple, the baby will be impressed.

Cognitive state

At this time, the baby can know common people and things. He began to observe the properties of objects, from which he would get the concepts of shape, structure and size, and even he began to understand that some things were edible and some things were not. Although at this time he still stuffed everything into his mouth, just to try. When you meet a toy you are interested in, try to take it apart and see the structure inside. If it's big, you know you need two hands to get it, and you can find out exactly where to store food or toys. At this time, the baby's life has been very regular, and he will defecate regularly every day. He also has an abacus in his heart, knowing that he can go to the park in the community after breakfast in the morning.

Emotional and social development

As time goes by, the child's self-concept becomes more mature. He has almost no obstacles when meeting strangers and separating from you, and he will become more confident himself. Like to be praised; Approach the child actively. In the past, you might expect him to be obedient when he is comfortable, but now it is usually difficult to do so. He will express his needs in his own way. When he becomes more active, you will find that you often have to say no to warn him to stay away from things he shouldn't touch. But even after he can understand words, he may act according to his own wishes, and he must realize that this is only a prelude to strong resistance.

At this stage, the child may show fear of the object or environment he used to adapt to when he was a toddler. During this period, fear of darkness, thunder and the sound of vacuum cleaner is common.

2, the game: the baby sits and plays with his mother, so that the baby and his mother keep a distance of one meter. Mother rolled the ball to the baby and asked the baby to "roll" it back. Mom takes the ball back, "rolls" it to the baby again, and then lets the baby roll back. Repeat it several times. Let the baby gradually master the skills of tumbling. In order to increase the fun of the game, mother can read children's songs during the game: ball, group, turn over, turn over.

The purpose of the game is to cultivate the baby's ability to control the movement of objects with both hands and experience the fun of parent-child games.
