So my DS1 has just started school and will be one of the first to turn 5. We had hoped to have a party for the whole class but found it was too expensive. Now we're planning to have a small party at home with about 12 kids, about 6 of these are from DS's class. We've picked the boys we've actually met up with outside school before. Since deciding this DS has had party invites from people we're not asking to his birthday. Is it ok to say yes if we're not including them in our celebrations. I feel mean!
