Final answer:
The claim that most children lose about 4-5 pounds during preschool age is false, as preschoolers typically gain weight and height with each passing year.
Step-by-step explanation:
The statement that most children lose about 4-5 pounds during the preschool age is false. During the preschool years, which generally refer to ages four to five, children do not lose weight but instead continue to grow at a slower rate compared to their earlier years. Preschoolers are expected to gain about 1.8 to 2.7 kg (4 to 6 lb.) per year and grow approximately 5.1 to 7.6 cm (2 to 3 in.) per year. It's important to note that growth patterns can vary greatly among children, but the general trend is for an increase in both weight and height during this stage of development. Growth in preschoolers includes improvements in motor skills, cognitive and psychosocial development, and physical changes such as getting ready to lose their baby teeth.
