Question

This age range typically sees a decrease in food intake and increase in rotary chewing. Which age range does this refer to?

1) 12 months
2) 18-24 months
3) 14-30 months
4) 6-12 months

Answer 1

The age range referred to is 18-24 months, which is when toddlers typically show a decrease in food intake and improvement in rotary chewing, corresponding with the development of molars and cuspid teeth.

Step-by-step explanation:

The age range that typically sees a decrease in food intake and increase in rotary chewing refers to 18-24 months. During this time, toddlers are transitioning from baby food to more solid foods and are developing more advanced chewing patterns. This corresponds with the emergence of their first molars (12-16 months), cuspid or canine teeth (16-24 months), and later their second molars (24-32 months). As their teeth develop fully, toddlers improve their ability to chew food in a rotary manner, which is more efficient for grinding down food.
