I’ve know for a long time to avoid “don’t/do not” this explains it a little better: Parenting Expert: ‘Do Not’ Doesn’t Work with Toddlers – Tinybeans

I think it keeps mattering because it’s easy to miss the “don’t” and only hear the rest. Plus it’s amazing how many ways people can follow directions while still not doing what you want.

Instead of ….. Try …..

Don’t run! – Walking feet! Walk please.

Don’t yell! – Inside voice. Quieter please. Lets turn down the volume.

Don’t go <place>! – Come back here. Stay right there.

Don’t climb/wiggle/stand/kneel on your chair. – Sit on your butt please.

Don’t touch that/things! – Hands together please. Keep your hands on your knees. Let’s try sitting on your hands.

Don’t <do this thing> without me! – Wait for me please.

Don’t <do this thing> without permission. – Ask permission and wait for an answer before you <do this thing>.

Don’t leave <thing> <wrong place>! – Pick up <thing> and put it <right place>.

Don’t forget <action/item>. – Remember <action/item>!
