what is expected before kindergarten for kids to do?

let them be at home and play... play with nature, animals, pets, trees, flowers, butterflies and most of all with the parents.. let the bonds be well established and closeness increase, the coming years are full of struggle only, dont start sessions of teaching as soon as it is into this world and expose it to the wretchedness and rat race of this world, a child needs to be calm , cool , soft and innocent... let it be so till it goes to school.DONT BE IN A HURRY, YOUR KID IS MISSING ANYTHING OR FALLING BEHIND OF ANYONE!!
