Our daughter is 18 months old. When she does something that irritates or make me angry she laughs/get happy.
For instance, when I sit by the laptop she comes by and push buttons on it. First, I say calmly that she mustn't do that. Then I clearly shows that I'm angry with that when she continues.
This is true for many situations.
Are there any known solutions for this and from where those this behavior come from?
Background info: In general we let her do almost everything she wants. We are not authoritative at all and wants her to have her freedom as much as possible. I have tried to punish her by locking her in another room. She really dislike that and cries. I let her stay there for a minute most. But punishing someone you love doesn't feel like a good solution.
