It is not unusual for some animals to play with toys. An example of this is a dolphin being trained to nudge a ball through a hoop. Young chimpanzees use sticks as dolls – the social aspect is seen by the fact that young females more often use a stick this way than young male chimpanzees. They carry their chosen stick and put it in their nest. Such behaviour is also seen in some adult female chimpanzees, but never after they have become mothers.
These views, grounded as they are on the perfectly well-ascertained occurrence of a former Glacial period, seem to me to explain in so satisfactory a manner the present distribution of the Alpine and Arctic productions of Europe and America, that when in other regions we find the same species on distant mountain-summits, we may almost conclude without other evidence, that a colder climate permitted their former migration across the low intervening tracts, since become too warm for their existence.
Pretend play is an essential part of a well-rounded childhood, helping kids develop intellectually, physically, socially and emotionally. By the age of three, your children will naturally begin to engage in pretend play, and you can ensure this activity is safe and rewarding by providing them with a good selection of age-appropriate toys. Make-believe must-haves include toy kitchens and play workshops, costumes, musical instruments and active toys like blasters and water guns. As your kids spend more time and energy in pretend worlds, their understanding of the real world will grow, and the skills they acquire will benefit them for a lifetime.
