A nurse is providing anticipatory guidance to the parents of a toddler. Which of the following should the nurse include? (Select all that apply.)

A. Expression of bedtime fears is common is correct because toddlers commonly experience fears related to separation, darkness, or unfamiliar situations. These fears are a normal part of emotional and cognitive development and should be addressed with reassurance and consistent routines. B. Importance of annual screenings for phenylketonuria is incorrect because PKU screening is performed at birth through newborn screening. Routine annual screening is not part of anticipatory guidance for toddlers. C. Develop food habits that will prevent dental caries is correct because toddlers are at increased risk for dental caries. Guidance should include limiting sugary foods and drinks, avoiding bedtime bottles with milk or juice, and promoting good oral hygiene habits. D. Significance of potty training by 18 months is incorrect because readiness for toilet training varies widely. Most toddlers are not developmentally ready until 18–24 months or later, and forcing early training can lead to frustration and setbacks.
