How do you discipline your toddler?

I have a 5yo and a 19m old. With my 5yo I'm able to talk to him and explain what behavior is acceptable. Challenge for a toddler as she usually puts up a mini tantrum. I just wait for her to calm down before talking to her. Whenever she did something unacceptable we always reprimand the behavior not he child. So far tantrums has lessened because toddler is able to grasps good behavior from previous explanations.
