1, there are many reasons for children's poor memory, some are congenital factors, and some are acquired factors, such as congenital diseases, congenital brain injuries and acquired brain injuries.

2. In addition, lack of oxygen, lack of sleep, overwork, anxiety and nervousness can also cause poor memory. Hypoglycemia, lack of some important brain nutrients, such as vitamin B 1, DHA and trace elements, can also cause brain function damage and affect children's memory.

In addition, memory is also related to heredity and acquired training. If congenital inheritance means relatively poor memory, insufficient training and insufficient nutrition, then a person's memory can be relatively worse than that of his peers.

4. Therefore, to avoid this factor that leads to the impairment of baby's brain function, reasonable rest, reasonable nutrition and active training are all conducive to improving baby's memory.
