Just wondering what other people’s views are on joint birthday parties? I always feel annoyed and try to avoid them now. It just doesn’t seem fair that the parents half their costs by planning together and expect the parents of the children attending to double their costs. A lot of parents who do joint parties expect people attending to buy two gifts (one for each child). What they should do (in my opinion) is create a guest list and let the parents know that they only have to get a gift for the one child who invited them. The vast majority don’t do this though!
