Nine-month-old baby development standard

After ten months of pregnancy, the time for delivery is finally approaching. After the pain of childbirth, the baby finally falls to the ground crying. At this time, don't think that it is the end. In fact, this is just the beginning. It is a long process from being a baby to growing up. When the child is young, we are all afraid that our child will be worse than others. At this time, we need to have a standard of growth.

So what are the growth standards for infants? In fact, there are different standards for infants at different stages of their lives. These standards are mainly to test the baby's sense of external stimuli, body development, etc. Below, we take the growth and development standards of a 9-month-old baby as an example to learn more about it.

A 9-month-old baby can easily move from a crawling position to a sitting position, and then from a sitting position to a crawling position, to get toys. If you cover his favorite toy at least halfway in front of him, he will be able to find the hidden toy. He can now pay attention to the smaller environmental sounds outside, such as: rain, wind, rustling leaves, etc.
