Raising a child is not easy.
It requires a superpowers if you are a mother.
With joint families in the past, I feel it was easier.
But in the modern world, where we are nuclear, it requires energy power and time management.

On top of this, the kid can get into mood swings. The tantrums can get in extreme mode. The society judges you on top of all this. There is fierce competition with yourself when you have decided on a life for your kid.
