Disciplining a toddler

To

I have a 2 year little girl. I do not want my child scared of me and I hate the philosophy that my child should be scared to respect me. But my child does things out of curiosity and some things I don’t like her to do. So what best work for you. I’m also a single mom which is a huge factor with me saying I don’t want my child scared of me. So what best work for you.
