Description ▷ If your child struggles with challenges and gives up easily, help them build 'this strength'! Imagine your child and a friend fighting over the same toy. If your child thinks 'I must get the toy right now,' what happens? They'll try to forcibly take it from their friend, who will resist even harder, and the situation could turn into a full-blown fight. But if the core question shifts from 'How do I get the toy right now?' to 'How can I get my friend to willingly share it with me?', the solution changes entirely. Your child might offer to trade for a toy their friend likes better, or suggest taking turns.
