My Dd aged 4 has been Invited to her first class party this weekend. She's excited. We have a card and preset etc but I feel very uneasy about it. I seem to be the one mum on her own at school. How can I feel at ease and make friends? Not wanting best friends exactly just people to chat with. This party is at a house so any tips on etiquette? Do I stay? How do I chat to people? Help please.
