DD2 (2.5) has picked this up from DD1 (6.5). DD1 usually says in the context of food or a tv programme or something, but somehow DD2 has turned it into saying "I hate you" to people.
She clearly has no concept of what it means.
But I don't know how to react to it. I've tried ignoring but then she just says it over and over again. I've tried telling her it isn't nice but she just smiles and says it again.
It's driving me crazy - and it hurts a bit, even if I know she doesn't mean/understand it. And we're seeing MIL at the weekend who will react and either get upset, or sulk, or come up with some outlandish 'punishment' that 'worked on DH'.
Any suggestions?
