Final answer:
Positive communication with preschool-age children is fostered by maintaining frequent eye contact, conversing at eye level, and including parents in the room to provide a secure environment.
Step-by-step explanation:
In planning care for a preschool-age child, open body postures that encourage positive communication include frequent eye contact and conversing at eye level. Leaning away from the preschooler may convey a lack of interest or engagement, while hands on hips can be perceived as a dominant posture, which may not be as conducive to inviting open communication with a young child. Including the parents in the room can provide comfort and security for the child, thus fostering a more positive communicative environment.
