Have a range of savory and sweets, and also some veggie options.

Things like quiches (homemade or bought)

Crackers with salmon and Brie/Camembert cheese

A platter with shredded lettuce, grated cheese, halved mini tomatoes, grated carrot, boiled egg slices, orange bits, blueberries, strawberry halves, dressings, shredded chicken, ham, turkey ect so people can pick and choose their own salads.

Homemade pikelets, with a container of margarine, jam and whipped cream for them to make as they please.

A platter of celery, carrot and other veggies "sticks" with cheese cubes and hummus

You can't go wrong with a bowl of chips and some dips

A baby shower cake of course

Muffins, savory and sweet

An easy hit - buy some French bread sticks (the long thin ones) and cut into about 2 inch thick pieces. Our some margarine, ham and cheese on each piece and put under the grill until cheese has melted.

Buy a box of chocolates and put these in a bowl - they were all gone at my baby shower.

If you intend on doing a large lunch, go for a BBQ and cook sausages, chicken ect, and have coleslaw and bread rolls for people to do what they please

U could make cake pops pancakes dip with crackers BBQ ice cream cookies and things like that good luck;)
