We want to do a simple party for our toddlers 2nd birthday at a local park. It will be for the parents too as all know each other. Any tips on what sort of food would work well for the adults and the children at this sort of party? I work full time so don't have much time to prepare stuff. Would you bring extra outdoor toys or just let the children run around and go on the playground while the parents take turns supervising and chatting? Would you bother with additional decorations or balloons?
