1, intelligent development characteristics ① large movements: this month-old baby can sit alone for a short while, let the baby prone position when the baby has the desire to crawl. If parents put their hands under the baby’s armpits and hold the baby standing, the baby’s legs have the action of wanting to jump. ② Fine motor: baby can hold things with both hands at the same time, grasp hanging toys, and can shake toys to make loud noises. Will still, drop things, play with toys can be interchangeable hands, see the mirror will want to touch. Speech development: They can unconsciously pronounce single sounds such as “Dad” and “Mom”, or sounds that parents do not understand well, want to talk, make different sounds to express different responses to different situations, and use body movements to express their wishes such as going out to play. ④ Self-care ability: Babies can put the pacifier in their mouths and suck milk by themselves freely. ⑤ Social interaction: can gradually understand the parents’ attitude towards the baby’s speech, can feel pleasant or unpleasant feelings, show unpleasant or even surprised or frightened feelings towards strangers, and will turn their bodies to familiar people. When they want a toy, they will cry if they can’t get it or can’t get it. 2, the ability to train ① sit alone: from 5 months of age baby sit training, after the baby hands pull the parents of two fingers to sit up, available pillows, etc. placed on the baby’s back to lean, and later according to the baby’s situation gradually removed behind the pillow, etc., at this time can also be toys, especially the baby’s favorite toys in front of the baby can reach the place, each practice 5-10 minutes, 3-4 times a day practice. ② Rolling and spinning: In a not very soft and flat bed or floor with a mat, etc., first let the baby lie on his back, using the baby’s interest in toys to attract his attention, training the baby from lying on his back to lying on his side to lying on his back, and then to lying on his back, so that he can develop the habit of rolling movements, while paying attention to safety. 3, cognition, language and communication ① Cognition: (1) baby sitting on the bed or the floor with a mat, etc., give him a toy, wait for the baby to hold it, then hand another toy to the same hand, guide the baby to pass the first toy to the other empty hand, and then come back to get the toy. So repeatedly, so as to train the baby’s toys to change hands skills. (2) baby’s small hands to grasp things, is to first learn to grasp large things, later will slowly grasp small things until 2 fingers to pinch small objects. Therefore, parents should let their babies practice grasping things with their hands, objects from large gradually become smaller, the object selected should pay attention to safety and health, can be small cookies, etc., do not use peanuts, beans, etc. to avoid foreign body inhalation. Training several times a day for several months, until the baby can flexibly pinch very small objects.

You should also teach your baby to recognize objects when they come into contact with them on a daily basis. Parents say “daddy” and “mommy” and let the baby imitate them, and train the baby to imitate the parents’ names for the objects when they come into contact with other objects. Take your baby and sing the song together, and do some actions according to the content of the song to facilitate your baby’s understanding of language. Generally speaking, 6-month-old babies can only learn one song and do one action. ③Life and Interaction: (1) When the baby cries for help, the parent’s hand can be extended to soothe the baby. But how to reach out is another art, perhaps this baby’s personality and ability will be born from this. For example, training baby to hold a toy, the baby can not reach too much, see the parents will cry and want to help, so when the parents directly to the baby’s hand will happen later similar situations, the baby will seek the same help from parents, and is not conducive to the baby’s ability to train and will cause the baby’s dependence on others. If at this time, parents help the baby through their own efforts to get the toy, not only to meet the baby’s needs, but also to exercise the baby’s ability to understand that only through efforts to achieve the goal. On the other hand, at this time, parents do not care about the baby’s crying, will make the baby lack of warmth and a sense of security. (2) At this age, expand your baby’s interaction with people, increase the number, and teach your baby to greet people with a smile or pronunciation. (3) Continue to practice the game of hide-and-seek and let your baby take the initiative to find the disappearing person or object. (4) Train babies to nod and shake their heads to express whether they are right or wrong, parents say “yes” or “no” while doing the action, and teach them to say “yes” or “no” according to the specific situation at that time. “”No””, and at the same time with the action that nod and shake the head, let the baby imitate.
