In the courtyard set up something like a mini summer garden for children: carousels, tires and so on. And among all put a large inflatable pool with boats for one person, such as skiing on the sea level) So, it is very pleasant when adult dads with one-year-old children in their arms, who do not understand what is happening at all, carry on each other with wild hiccups, clash, crack.... )) Children are just a cover!
