To be childlike is not to be childish!
Perhaps it is because small people are nearer to the ground that they see small things we miss? Or they are newer to the world and are still learning to see and notice things? To be childlike is not to be childish, let your eyes be fascinated by your surroundings! For anyone who has lost their inner child, I would prescribe an outing to The little Angel Theatre to rediscover what it is to imagine at play and a reading of "The Velveteen Rabbit" by Margery Williams. A dose of magic and finding out what it is to be real!
