It's difficult to estimate numbers, but I think not less than 10 percent of those present in Tahrir were families. They added a special spirit to what we started calling Republic of Tahrir. Some of the kids would do their own marches around the square, with people applauding and smiling at them. They were quite an integral part of the place and everyone took care of them. When Tahrir would get crowded and a kid got lost from his parents for a while, we would quickly mention their name in the large microphones set in the square and the parents would easily find them.Did You Know There Was a Pop-Up Kindergarten in Tahrir Square? (Thanks, Rufusstripe, via Submitterator!)
I wouldn't say the kindergarten idea was set up by specialists. But there were people of all professions in Tahrir which obviously included teachers. But many of those working on the kindergarten were ordinary mothers who would take care of the kids and look over them while they were painting or reading. It was usually set in the safest area of the square, just in case anything would happen, and the kids were being kept at a distance from any possible tension. But obviously it wasn't professionally set up. I mean, it didn't have working hours or a fixed schedule, because the place was quickly developing and changes were taking place from day to day. Still, the main core was maintained and any kid could join, play with others for some time, and indulge in children's activities for a while. It was quite heartening to say the least.
