Im planning a birthday party for my eldest who is 3 in a couple of months. She has certain friends at nursery she talks about but we’ve never met the parents …what do people generally do / I thought about asking her key worker to pop an invite on the bags of these children for their parents with our contact details etc on but is it weird if we’ve not met them?! She’s quite new to the nursery so I’ve not really met any other parents yet..she was moved up early into preschool.
