Get down to their level to give support and eye contact. Sometimes sitting down helps to show you are listening and available.
Listen more and talk less- if we want our children to be good listeners we need to model the desired behaviour.
Children rise and fall along with our expectations- let your child know you believe in them and their many wonderful traits; and that you trust them to make a positive choice.
Disarm the moment with empathy- "I understand it's disappointing that we need to head home now".
Offer them a two choice frame. "Would you like to run to the car or jump? When we get to the car would you like to listen to Mummies songs or your songs?"
