Activities at birthday party?

So far the ages of children coming to my daughters first birthday are a 7 year old boy, 5 year old girl and 2.5 year old girl. I think there are going to be a few more but not sure. I am going to print out a few different coloring pages like princess, halloween, batman and what not for them to covities to lor. I have goody bags with some toys and candy. I would like to have a few other games/ activities for the kids that will not cost much at all or even free. This party is mostly adults just a few kids and its like a big dinner get together. we live in a apartment with no outdoor play area so its inside only.Activities at birthday party?
pass the parcel with simple things in each layer (lollipop, stickers etc).

lego or other building blocks and a ramp to race their creations.

treasure hunt (again very simple) and can be indoors

dance and freeze (play music and when it stops dances have to freeze, move and you are out, get the kids to judge the adults, an absolute hoot)

Dont underestimate a new release cartoon video

play doh

ask the parents to bring a game or two of their children.Activities at birthday party?
Yep pass the parcel is a good one and maybe a big floor puzzle. is there a toy library at your local community center you can borrow some games and toys maybe?

see if the library has any cd's with games and music for you to borrow and clear out any unneeded furniture in the lounge room so the kids have room.
