Parents at least have the responsibility to send their children to school up to 9 years old. We know the term 9 years of compulsory education because children cannot be required to find their own way to pay for their schooling. And I don't agree that if parents only cover their children's school fees up to elementary school, they are not responsible for supporting their children's education for future needs, even though their children will replace the backbone of the family when their parents retire or get old. So educate your children until they reach higher education and parents must monitor their children's activities at school so that they are not negligent in other things that are detrimental to themselves.
The first responsibility of a parent to the parent is to send the child to school and every other thing will come when the child is already enrolled in a school. And when they get to some certain age that way they will be able to add up other things. But their education still comes first because through education they can be able determine what they want to become in the future. As far they have a child they must be ready to take responsibility of the child starting from their welfare and education till when they are capable to be responsible for their self. Reverse is always the case when the parent are old the children will take care of the parents, they can also take care of their self so parents need to seriously invest in their children to benefit later, and couple with the fact that education is very important.
