She's had it since she was a new born and I've never taken it away from her. I've never seen the problem with letting her have it to settle to sleep, but now she's got a school trip coming up after Christmas and spending two nights away. She's really excited about the trip but I know that if she takes her dummy she will be teased by the other kids, which would be terrible. I feel like the dummy needs to go for her own good but she is very reluctant to give it up. No idea which approach to take with this, any tips?
