Climb the cave: put the carton horizontally on the ground, roll the ball in and guide the baby to chase. Because of the narrow space, he will crawl naturally and can exercise his limbs and balance. Over the mountains: pile up blankets, pillows, quilts and other items at home into various obstacles, let children climb up and down, and learn to use their bodies and limbs comprehensively. The purpose of jumping practice is to exercise his explosive power, jumping ability and balance ability. Climbing and jumping: prepare a stool or chair about 10~ 15 cm high, or a bed and spring bed at home to help the baby climb up, then hold the baby's hand with both hands and teach the baby to jump off with both feet from a height. After the child jumps skillfully, let the child jump constantly and gradually increase the height. Jumping obstacles: put a colored rope or toy on the ground, or draw a circle on the ground, or stick a colored tape on a river of about 10 cm, so that the baby can jump over it, or jump from one side of the river to the other, which will trigger his explosive force to gradually form. Jump shot: tie a rubber ball with a rope and hang it above the baby's head. Babies can jump up with their feet and hit the ball with their hands. At first, you can hold his armpit and help him take off and land smoothly. Then you can adjust the height of the ball according to the baby's bouncing ability. 3. The purpose of walking training is to achieve the initial balance ability and walking ability. Take a narrow path: draw a line with chalk or make a narrow path with two ropes, let the baby walk independently on the ground along the drawn route, or lead the baby to practice on the outdoor square brick road. Slope walking: Prepare a wooden board with a width of 35 ~ 40cm and a length of about 1m, and make a slope with a height of about 10cm at one end, or use the natural outdoor slope to help the baby walk up the slope with one hand at the beginning. When the baby is steady, encourage him to walk alone on the slope without your help. Cross the river with stones: You draw two lines on the ground with chalk as a big river, and draw some circles in the river as stones, telling the baby that you can only cross the river with stones, or you will fall into the river. 4. The purpose of developing whole body movements is to promote the development of children's whole body movements. Travel around the world: use 20~50 cm square cartons of different sizes to make large hollow or solid building blocks, and let the baby stack the building blocks, or carry them, or push them around the room. The resistance of pushing objects can increase the proprioception of children's joints and promote the development of whole body movements. Climbing scaffolding: take your baby to the climbing frame of children's playground or kindergarten, and teach your baby to grasp the crossbar above and the crossbar below the pedal by hand and climb up step by step. As far as the physical development of 1~3-year-old babies is concerned, the focus of this stage is to promote children's sports development, especially their balance and coordination ability. With the increase of activities, the danger will always exist, so parents must observe and supervise carefully and not take it lightly.
