Over the years [cough] I have witnessed oodles of kiddies parties and witnessed the shocking left over food, some just untouched!
The idea I had when my kids were small [back in the 90’s] was to have themed party boxes with each guest’s name on, containing a selection of party foods which can be wrapped, some fruit & a toy. Oh and later a piece of cake! You can get these on-line from most party supply sites.
There was always enough space left in the box to collect any small prizes during the party so when Mum or Dad came to collect them, they took their box home with them leaving us we very little clearing up to do!
If you would like to see more tips, let me know! Colleagues have often said I should write a book on the subject!!
