I've just taken DS (10 months old, he's standing, cruising and crawling) to a small local soft play with my friend and her baby. It's a very expensive smart newish one with a small amount of basic stuff and a cafe - not a jungle gym with slides etc suitable for bigger children
Dear Lord it was hideous. Parents on their phones not supervising or even vaguely keeping an eye on their children, our toddlers nearly getting trampled despite keeping them to a small corner away from the more grown up bits. Boiling hot and sticky. And the screeching.
Never again. Never.
