Reduce Your Language
Sometimes in the “tricky moments” our tendency can be to use a lot of words to our toddler. The ability of your toddler to process language at any stage of the tantrum phase is limited. The extra demand of processing your words might in fact pour oil on the fire.
If in doubt zip it up or use 1/2-word directions only. Alternatively use non-verbal cues such as gesture or a photo/visual of what you need them to do. Having a small A4 whiteboard to draw on is a good tool to have in your toolbox. Non-verbal communication at any phase of a tantrum is super effective. Also, avoid asking them any questions in any stage of the toddler tantrum.
