Ok, think we have the bare bones (!!) of a theme agreed (although birthday boy only 3 so may change his mind). About 11 children, 5 are 3yrs; 4 are 5yrs with two 7yr olds. More girls than boys. Need some ideas for games, have access to sports equipment. Hoping to be in garden/ park, but may need to modify if wet.
Ideas so far:-
Hunt for mini dinosaurs in sand (thought one box per family so older siblings help younger ones)
Dinosaur (chocolate) egg hunt
What's the time Mr T-Rex
Parachute game with mummy dinosaur and her eggs (balls) - have to keep the balls on the parachute.
Walk around room pretending to be dinosaurs (can do to music if inside)
I guess we could throw in a pass the parcel.
Any other ideas for games? I am assuming that most of the LO will be swept along with their older sibling, so can be a bit more complex than a normal 3yr old party.
