This is gorgeous, that's why children are always happier and they make world shine with their smiles, for them everything is possible.
And you are right, some parents just say ''no, you can't'' and they don't realize that when children have the parents support for everything, they feel unstoppable and are more capable, have more confidence for making their dreams come true once they grow.
I never understood parents who forced their kids to follow their footprints into a career or predetermined path. Or those who kept on telling their kids they were wrong without helping them discover a solution to the problem.
