DD is 4.5, and in the last few weeks of nursery. Her classmates are largely a lovely group of children, but there are two girls in particular who seem to delight in name calling. Unfortunately dd seems to regularly be on the receiving end of their childish insults.
I know this is a natural part of childhood development, but would like suggestions from experienced parents about what to tell DD to do when she's called "poo poo head" or told "you're not my friend" or some other 4 year old insult. Poor thing feels upset, and I'm afraid that response will fuel more insults when others see she is being wound up. She needs to learn to stand her ground now so she's not a target in future. What can she say/do to nip it in the bud?
