The main difficulty we have found with this stage is that preschoolers have a definite mind of their own. While they are often open to negotiation, they also tend to have strong opinions about what they want to do. A baby doesn’t have to be persuaded to visit an art museum, and a toddler just sees it as an opportunity to do more running, but a preschooler may need bribes to abandon what he’d rather be doing (in all likelihood, watching TV in the hotel room or swimming in the pool).
