a small portion from the article:
So here, I offer my list of what a four year old should know:
She should know that she is loved wholly and unconditionally, all of the time.
He should know that he is safe and he should know how to keep himself safe in public, with others, and in varied situations. He should know that he can trust his instincts about people and that he never has to do something that doesn't feel right, no matter who is asking. He should know his personal rights, and that his family will back them up.
She should know how to laugh, act silly, be goofy, and use her imagination. She should know that it is always okay to paint the sky orange and give cats six legs.
He should know his own interests and be encouraged to follow them. If he could care less about learning his numbers, his parents should realize he'll learn them accidentally, soon enough, and let him immerse himself instead in rocket ships, drawing, dinosaurs or playing in the mud.
She should know that the world is magical and that so is she. She should know that she's wonderful, brilliant, creative, compassionate and marvelous. She should know that it's just as worthy to spend the day outside making daisy chains, mud pies and fairy houses as it is to practice phonics. Scratch that -- way more worthy.
But more importantly, here is what parents need to know: http://www.drmomma.org/2011/11/what-should-4-year-old-know.html
