I think you can ask more friends around you, and you may get a more accurate answer. In addition to early education, there are many ways to learn, such as playing games with the baby, teaching in the process of life, reading and drawing, but this thing is easy for the baby to eat and not vivid enough.

My daughter has been exposed to Chinese characters since she was three years old and has been literate for more than 300 years. Basically, she learned it from software. There are many animated stories in it, which babies especially like to watch, and there are games to play (games are to consolidate literacy). At first, I was worried that playing too long would be bad for my baby's eyes. Later, I found that there was a setting function in it, which could set the study time and automatically turn off the use time. That's great. Long-term use has also exercised the baby's eye habits. Baidu searched for cats (what) to learn Chinese characters, and the answer was that Xiaoshuai now learned more words and listened to more stories. Come back from work and tell me stories. It's super warm (though intermittent, it's super cute).
