We know, we know---we said 'kids of all ages', and that was mostly correct. For the safety of everyone who enjoys these toys, you'll want to keep extremely young infants off of the bounce houses and inflatable slides ; and keeping kids of similar ages and sizes on the bounce houses and inflatable slides at the same time is a good idea. In other words, while these are certainly great tools for family fun, perhaps it's best that the whole family doesn't enjoy them at the same time !
