Having a barbecue for DDs 1st birthday this weekend. Gone all-out on food (chicken, sausages, ribs, burgers, salads, potatoes...i.e. not just burger in a bun type-thing) and made puddings etc. Invited about 20 friends with their children. As it’s DDs birthday, I would suspect everyone will bring her a present so would I be unreasonable to ask people to ‘bring a bottle’? Opinions please.
