Planning DD's 4th birthday party. Just her nursery class and cousins invited - about 25-30 kids. I've hired a hall (for free as it is part of the school where I work). Food served will be reasonably healthy 'picnic' type food (sandwiches, pasta salad, carrot, cucumber, tomato, peppers, fruit kebabs and a few crisps ). WIBU to just put sweets/edible things in the party bags? I don't want to buy loads of plastic tat, but I'm worried I will annoy parents if I send the kids home with sweets and cake. I'm open to other bright ideas, except not doing party bags because I like to do them. They are a good signal that the party is over. Thanks.
