What I understand the main problem is how children are raised. With you I find it strange if children, boys and girls, go out late or hang around on the streets.

Since we live in 2024!! I wonder why the role of boys/men is not mentioned.
If this is all dumped on the shoulders of a girl and there is no support it is up to her to decide what to do with het body and life.
If she decides to keep her child she should be able to provide in the needs as well. This is not the task of the (grand)parents or society.
