Social referencing – looking at you to work out what’s ok
This seemingly cheeky little look is often put down to ‘trying to get a reaction’, which is in fact absolutely what they’re up to!
Your toddler is looking to a more experienced person to see what they think of the idea, and they will use that person’s reaction to inform their decisions: should I climb this step/touch this pan/approach this cat?
If your reaction is fearful, your toddler will be less likely to carry on with their potentially hazardous mission!
