Ds is five turning six. He's asked for a birthday party with friends from his class this year. Usually we just have adult family members round to the house. I don't fancy having a kids party at my home so I've looked into a birthday party at the local soft play which I know he'd love. He's a really friendly and popular little boy so he's friends with most of the other children in his class. I don't think I can afford a party for 20 kids. Min number to book the party is 10. Would it be okay to only invite half his class? Is that mean to those who don't get invited? I know they're young but I wouldn't want this to cause any problems with the kids who don't get invited. Am I overthinking this? I was painfully shy at school so I'm very wary of making a child feel left out. Any advice?
