"I like ___ because ___. Can I help you ____?" is a great opening sentence to rehearse with your kids, says Julia Simens, author of Emotional Resilience and the Expat Child. "For instance, your child could say, 'I like your tall building block hospital because it looks like a real place. Can I help you add a parking garage?'" When your child is positive and specific, she's less likely to get turned down.
