I didn't really know what to do for DS first birthday, and I didn't have access to much so I just it a funky balloon to a lollipop. Woolies has the different shape balloons & just got a mega bag of cheap lollipops. That way they didn't get too much & I guess the parents didn't have to stress too much about what they couldn't have in the bag LOL. All the older kids loved it. I must admitt though I loved getting goodie bags when DS was too young & eating it all myself LOL!!!
For his second party I was better organised & had more access to stuff...but still didn't want to fill the bag with bits & pieces as I didn't know where to start. So I put in a spinning top or bouncy ball that I got a the cheap shop. Then I took the idea of the cup cake decorations from the womans weekly birthday book & iced biscuits instead. They were made to look like lions as we had bit of a jungle theme going & just put them in the bag with the toy.
