Hey, you are a mother of three children, why are you still so childish? What do you mean?

“You are a mother of three children, why are you still so naive?” means: You have three children, but you are still so immature.

This topic reminds me of my sister:

My sister has a very simple character and speaks straightforwardly. She doesn't hide herself when she's angry, and she even does whatever she wants, so she feels like she's in a childish state.

Later she got married and had children. Although she learned a lot while growing up with her children, overall she matured very slowly. For example, when you are angry with your brother-in-law, you will not deal with it calmly. Not managing your emotions well. There is also the problem of not looking at the long term and always looking at the present.

With such a character, my parents often lamented: Why can’t I grow up? When can I grow up?

Yes, whether a person can grow up is related to her experience, but it mainly depends on her character. Some people's personalities are always in a pure state, and it will be difficult for them to grow up if they have little experience. Therefore, it has little to do with how many children there are.
