BBQ for 3rd birthday party - what food and how much?

[AuntieMaggie]

Hosting a BBQ for nieces 3rd birthday - what food would you expect to see? And how much?

I was thinking burgers, sausages, salad, coleslaw, maybe some grapes and strawberries and squash for the kids... and obviously birthday cake. Is that ok do you think? Would you bother with 'nice' burgers and sausages? And is one each ok?

Will adults be eating too? If so I think you need to allow more than one burger/sausage per person.

I'd also provide some sort of carb - bread rolls or a couple of trays of oven chips.

I was going to do rolls for the burgers and sausages... its not really a meal time bbq but a kids afternoon party between 2 and 4
