Is It Advised to Always Say Away to a Child?

If a child's level of distress is going to 10 out of 10 then it's not you know at a particular separation it's time to take a step back maybe and um maybe that particular child might need to go to a different child reminders or you need to reassess the situation so I often say to parents to kind of keep a little diary of how distressed your child is getting in particular situations. Is it advised to always say goodbye to a child? "I feel it's better if they know yeah but no it's a hundred percent better if they knows"
