Babies under one year old are suitable for stretching and crawling, because the baby's bones are fragile and the limbs are weak. Stretching and crawling can exercise the patience of bones and muscles. In addition, in the process of crawling, the baby is often in the state of "collar neck", and the neck muscles are well exercised, which is conducive to the development of hearing, vision and touch, and really plays the role of "hearing and seeing".

Guide the baby to reach out and grab: as the baby grows up, you will find that he is no longer always holding his fist, but is always ready to open his hand to grab something. Then it is more appropriate to give him a game pad at this time. Hang some toys above the baby to lure him to grab them. The whole process needs the cooperation of hands and eyes, which is also a key step in the development of sports ability. Therefore, prepare some toys that can be grasped, so that the baby can keep practicing and improve his sports ability. Of course, it would be better if you can choose things with different materials, which can give children different sensory stimuli and improve their cognitive ability.

Bathing: Bathing is also a good time to exercise your sports ability. Prepare some toys in the basin for him to pat, so that the splash will make him very excited. But be sure to pay attention to the safety problems when taking a bath.

How to make children develop a good habit of loving sports;

1. Help children find sports that suit their personality. Some children like ball games, such as baseball, football and tennis. Others like swimming, equestrian, gymnastics or sailing. Observe the child's advantages and disadvantages, as well as his likes and dislikes. Let children try several different sports until they find the one that suits them. You may have played baseball all your childhood and still love it, but if your child likes swimming, you should support his choice and encourage him to try your favorite sports in a friendly way.

2. Find a sport that you can participate in with your children, such as military games, swimming or tennis, and have classes together. Children like to get the attention of their parents, and they will gradually like this sport in the process.
