Wow this is really a beautiful idea, I have had so many different experiences although there are different ways of learning and also Understanding, because the way I understand a particular topic might not be the same way for my kids.definitely children are always known for asking too many questions and you must always be ready to answer them, because they want to know what it is and how come about it existence of which it is a good one if you don't questions about a particular thing there is every tendency that you will always be a left out. It's a good idea that as we parents we must always be ready to teach even though they have been taught in school about a particular topic and they will also turn out to be your teacher in other words this calls good Communication and interaction with your kids and as time goes on they begin to tell about different methods of any topic they come across and also it's a good one when you point out a particular or different objects and they are able to identify when they are opportuned to see it again, Thank you so much for this information.
