Hello! DS will be 2 in a couple weeks (which blows me away!), and I'm having his party at a playground. I rented a pavilion and we're having cake, but that's it for the planned activity. I wanted the kids to be able to just play and have fun (no gifts, etc.). I'm thinking about whether I need some sort of activity for them to do all together, though... The ages will range from 9 months to 6 years old, so obviously they won't all play together doing the same thing. I thought I'd just get some bubble stuff and let them play in it. For the younger ones that walk but don't blow on bubble wands themselves, they'll enjoy running/walking through them and popping them. Cheap and requires no clean up... Does anyone have any other fun/cheap/easy ideas for outdoor activities?
