some babies were quietly sitting there , being pushed along in the sunshine with not a care in the world whilst others were screaming as if they were being attacked by a pack of wolves , their bodies jolting , legs and arms kicking and flailing everywhere as if they wanted to be free from their mobile prisons , so they could cover themselves in chocolate and dirt and be fascinated with anything and everything , from a bird flying past to someone who was fat or ginger , or even worse , both .
