Why do preschoolers often eat less than they did as toddlers?

-Preschoolers tend to be more distractable and finicky than toddlers. It's a time of exploration and something preschoolers will decide they don't like a food for no apparent reason. Sometimes its just them taking some control in their lives.Because they aren't growing as much and they tend to be less "busy" so they need fewer calories. Perfectly normal.
My preschooler actually eats better than she did as a toddler.
