My child is soon leaving nursery to start school, I was going to buy the staff chocolates as a thank you, I have done this each time dd has moved up a room at nursery. I never wanted to go overboard with gifts and have never asked anyone else what they do, but yesterday I overheard a group of mums talking about what to buy nursery staff, they said that hocolates are t enough and started talking about expensive gift vouchers. I've never doubted myself before wih this but now I'm wondering if I've committed a faux pas? Please can you advise me on what's normal? Thank you
