Analyze the reasons:

1, each baby's understanding ability is different at different stages of development. Although everything should be known sooner or later, it is also important to give the baby proper enlightenment at the right time.

2. There is little neighborhood communication in city life. It is a luxury for a baby to find a childhood playmate, and the baby needs to have his own social circle.

3. Everyone knows that parent-child interaction is very important, but self-disciplined parents are really pitiful, not just playing mobile phones or computers while watching their babies. I can really play, laugh and have fun with my baby. At this time, I say that if there is, it will be pitiful, and if there is no, it will be pitiful.

4, mothers also need to communicate, even if they understand the various problems that may arise during the baby's growth.
