DD is 3 almost 4.
98% of the time she's happy, chatty, funny, bright, engaged, busy.
The rest of time she's full of tantrums, tiredness, bossiness, anger. So pretty standard for her age.
But she's brutally honest and when challenged can back it up. It's a particular issue with grandparents and whenever she sees them she runs from the room and says she doesn't like them.
I've explained it's hurtful and upsetting but she says she wants to upset them. We've talked about words hurting people and being kind but she's adamant she wants to upset people.
Not sure how to handle it.
