DD's just two and her new thing, if she doesn't get her own way/bumps her head/isn't allowed a biscuit is: I want to go home! (in a whiney voice). She doesn't necessarily mean it because she even says it when she is home, but how can I discourage it? Ignore it? It gets a bit embarrassing, say if we're visiting friends or relatives. Please tell me this is just a phase! Thanks.
