• Musculoskeletal Development: Bones continue to ossify (harden), and muscles become stronger and more coordinated. This allows for increased strength, endurance, and agility. The cartilage in their bones continues to convert to bone, but growth plates remain open, indicating ongoing growth.
• Dental Development: By age three, most children have a full set of 20 primary (baby) teeth. Throughout this period, tooth care becomes increasingly important to prevent cavities, which can impact speech and eating.
• Brain Development: While not outwardly visible, brain development is rapid. The frontal lobes, responsible for planning, organizing, and self-regulation, continue to mature. Myelination, the process where nerve fibers are insulated, speeds up neural transmissions, contributing to faster and more complex thought processes and motor control. This brain maturation underlies many of the cognitive and motor achievements observed in this age group.

 

Sleep Problems in Early Childhood

  While sleep needs decrease slightly from toddlerhood, children aged 3-6 still require a significant amount of sleep, typically 10-13 hours per 24-hour period, which may include a daytime nap for some younger preschoolers that gradually fades as they approach kindergarten. Common sleep problems in this age group often stem from developmental changes, learned behaviors, and environmental factors:

• Difficulty Falling Asleep (Sleep Onset Latency): This can be due to an irregular sleep schedule, overstimulation before bed (e.g., screen time, energetic play), anxiety about being alone, or a lack of a consistent bedtime routine.
• Night Wakings: While less frequent than in infancy, children may still wake due to nightmares, night terrors, or a need for parental reassurance. Nightmares are frightening dreams that awaken the child, who can often recall parts of the dream. Night terrors, less common but more dramatic, involve partial arousal from deep sleep, where the child screams, thrashes, and appears terrified but is often not fully awake and has no memory of the event the next morning.
• Resistance to Bedtime: As children gain more autonomy and experience FOMO (fear of missing out), they may protest bedtime with stalling tactics, requests for drinks, or repeated calls for parents.
• Sleep-Disordered Breathing: Though less common, enlarged tonsils and adenoids can lead to snoring or sleep apnea, disrupting sleep quality.

Establishing a consistent, calming bedtime routine (e.g., bath, story, quiet play), ensuring a cool, dark, and quiet sleep environment, and addressing underlying anxieties can help mitigate these issues.

Sample Answer

           

As the school nurse for our local elementary school, I'm happy to share some valuable information with our community regarding the fascinating development of children between the ages of three and six years old. This period, often referred to as the preschool or early childhood years, is marked by significant physical, cognitive, and social-emotional leaps.

 

Physical Changes in Children Ages 3-6

  Between the ages of three and six, children's bodies undergo a noticeable transformation from the more "toddler-like" proportions to a more streamlined, "school-aged" appearance. Growth tends to slow down compared to infancy and toddlerhood, becoming more gradual and steady.

• Growth in Stature: Children typically grow about 2-3 inches per year and gain approximately 4-5 pounds annually during this period. Their bodies become leaner, and the potbelly often seen in toddlers begins to flatten as their abdominal muscles strengthen and their trunk lengthens.
