No is one of the first words children hear. They are bombarded with angry tones and irritated “No’s” throughout their lives. And for the most part the word is ineffective. The child becomes more likely to go and do exactly what you told them not to. There are better ways
As a daycare teacher I consistently hear “redirect”. It’s what we’re told to do when a child does something inappropriate. Redirect means to show the child something else, or to show the child the proper use of what their handling. If a child is about to climb on a chair you could say “look at this, look at this _” And show them a toy or an activity that, preferably, they like. Or show them how to sit on the chair so that it’s safe as long as the chair is age appropriate.
Also instead or no and don’t give them other directions that are still short. Like “get down”, “walk”, “quietly”, and “gentle”. These dire tions are easy to hear and simple so it’s easier for the child to process than don’t run and don’t hit.
At the end of the day it’s important to know that children don’t just mirror actions but they mirror moods too. They need affection to grow but they’re also trying to explore the world and learning independence at the same time which is a big ordeal for such small creatures. They need us to show them a better way to behave.
