Hi, I am Margaret Rodgers. Thanks for your great article. Actually, My kids are zeal of playing with the bounce house. When I see their joy knew no bounds then I feel very happy. I think they are much more secure than the toys you might give your kids. Toy parts can be harmful if swallowed and this is not the case with any bouncy products. My doctors have also said that kids who want to grow taller should be consistent in jumping and reaching for higher objects this stretches out the bones improving their height.
