This is a much debated topic. Until recently, experts agreed that over-stimulation of children is harmful, but recent research data challenges this theory. In fact, it is known today that the pace of development of children of the same age, is quite different depending on their country of birth. It has been found that the environment does have a slight influence in speeding or slowing development. Parents should realize that everything around a child, including people, influences its development, helping or hindering it.
