The two universities made these conclusions after studying the results of an economic survey in Germany.
This survey looked into the daily routines and habits of 800 parents with two and three-year-olds.
It recorded higher perceived levels of happiness among the children who had taken part in activities such as arts and crafts, and shopping.
Researchers Professor Paul Anand and Dr Laurence Roope added that the more retail therapy the toddlers were exposed to, the happier they seemed to be, and the more developed their everyday skills became.
Shopping may be beneficial because it involves changes of scenery from shop to shop, which improves the child\’s motor and social skills more than a sedentary activity, the report continued.
