DD1 is 5 and in year 1. She is, for the most part, absolutely lovely - kind, polite, clever, thoughtful to others etc.
However she has a habit of declaring that she is an expert at things. The best. The very best. Ask anyone. Often about things that she’s just tried once, doesn’t really understand, and definitely isn’t a world renowned genius at.
It’s like having a tiny pint-size Trump twitter feed always on. I am just grateful she hasn’t learnt the phrase “fake news” yet. I have tried subtly hinting that this isn’t the done thing, I have tried flat out telling her not to, I have tried ignoring. She seems to have it hard-wired in and does it without thinking.
Do other DC do this? Is it a phase? Is there a tactic that works to stop them?
