My DD started preschool mid term, she's made a few friends but I haven't met any of the parents yet. Her birthday is in a month and I have to decide if we do something small at home for family friends or invite the whole class (33 kids, 15-20 pounds per child at a venue). She's been invited to two parties that will happen after hers. I need to send invites now if it's to happen at all and it does feel strange to invite strangers to a birthday party, equally it doesn't feel tight to attend everyone else's without arranging something ourselves?
