I would say both parents are. It depends on how much time and effort they invest in their child. In some cases grand parents are more involved in education of children in the family as parents may work a lot. In my country we care greatly about kids education. Kinder-gardens, schools, many public events are all made family oriented and provides fun activities that’s boost creativity. But it is with in the family to recognise the interest and potential of your child to guide him/her in the right direction, help to learn and become a successful in life. :)
