I do on site balloon decor for weddings parties etc so I have tons of balloons at home!! Nathan first of all does not like the sound of the machine I use when i blow up the balloons and he will play with a air filled balloon if it is on the ground...otherwise he wants nothing to do with them!!!
Which is good !! just be careful because a popping balloon around their face can be harmful ..I know i have gotten popped in the face a couple of times by a popping balloon but they are funny trying to chase something usually bigger than them!!!
