Some great ideas, thanks everyone... hmmm 1 week til the party, better get myself sorted!
The jewellery etc will be one piece things with no beads or breakable bits, the whistles i am doing as a thing the MUM can do for the kids, DD has already learnt to blow a whistle as my MIL gave her one in a toy bag for her 60th birthday, DD loved them so thought might be something cute.. wont be too little though.
