I think its difficult to not be a helicopter parent to some extent because if you don’t bust a gut to get opportunities for your child then they won’t have the chance to learn how to be independent.
Looking back on my own education far far too much of it was purely academic. For example in food education I learnt how to design packaging for food but little about how to actually cook for a family. I was taught how to pass exams and not much more. In my country under the current government it seems that the emphasis is still firmly on the academic.
So if as a parent you just rely on schools to prepare your children for the wider world I think you are going to be disappointed.
I think the best thing you can give them is your time, and that’s what I hope to do for my child.
Spend time with them in the wider world teaching so that they learn from example. Teach them the basics of how to run a home. Also teach them to think for themselves. If you can give them the opportunity to interact with as many different people as possible, not just kids their own age.
