Navigating Sleep Development: Insights from a Board Certified Behaviour Analyst

Understanding the developmental milestones of sleep in children aged 2-6 years old is essential for caregivers seeking to establish healthy bedtime routines and promote optimal sleep habits. As a Board Certified Behaviour Analyst (BCBA), I recognize the significance of sleep in a child's physical, cognitive, and emotional development. These milestones are standard across all children (i.e., with a diagnosis of Autism, ADHD, Anxiety or no diagnosis). Let's explore the developmental milestones of sleep during these formative years: 


The Toddler Years (Ages 2-3): 

Transition to One Nap: Toddlers between 2-3 years old typically transition from two naps to one. This transition may disrupt established sleep patterns and require adjustments to the child's daily routine. Think about how you can keep some consistency in routines that will queue nap time. 

Establishing Consistent Routines: Implementing consistent bedtime routines is pivotal during the toddler years. Predictable sequences of activities signal to the child that it's time to wind down and prepare for sleep, fostering a sense of security and predictability. This can look like dimming the lights, reading a book or listening to some lullabies and snuggling in a chair, turning on a sound machine and closing the blinds. 

Addressing Nighttime Fears: Toddlers may experience nighttime fears or separation anxiety as their imaginations develop. Acknowledgement, reassurance and comfort from caregivers can help alleviate these fears and create a sense of security at bedtime.  

Preschool Years (Ages 3-5): 

Regularity in Sleep Patterns: By ages 3-5, children typically settle into more regular sleep schedules with consistent bedtimes and wake times. Encouraging a structured sleep environment and reinforcing bedtime routines can further support the development of healthy sleep habits.  

Individualized Bedtime Rituals: Preschoolers often develop individualized bedtime rituals or preferences. Acknowledging and incorporating these preferences into the bedtime routine can enhance the child's sense of autonomy and promote positive sleep associations. Think about offering choice around which books are read and where, what stuffy to sleep with and who reads them at bedtime. 

Managing Nighttime Wakings: Nighttime awakenings remain common during the preschool years, often due to dreams or discomfort. Employing strategies such as positive reinforcement and fading parental presence can help children develop self-soothing skills and return to sleep independently. You may try comforting your child briefly by sitting on the bed instead of laying down with them, then sitting in a chair in their room, then leaving an coming back to check in. 


Early Childhood (Ages 5-6):  

Optimizing Sleep Duration: Children aged 5-6 typically require 10-12 hours of sleep per night to support their physical and cognitive development. Monitoring sleep duration and quality is essential during this stage to ensure children receive adequate restorative sleep. Stay consistent with bedtimes and wake time, routines and healthy sleep dependencies like a favourite blanket, pillow, sound machine and black-out curtains. 

Promoting Independence: Early childhood marks a transition towards greater independence in bedtime routines and sleep habits. Encouraging children to take an active role in their bedtime routine and providing opportunities for self-regulation can facilitate the development of healthy sleep habits. Things like choosing an audio book to listen to before bed, helping them to identify when they are tired by highlighting physical cues that you note (e.g., rubbing eyes, yawning, crankiness). 

Setting Firm Boundaries: As children become more adept at negotiating bedtime, setting firm and consistent boundaries is crucial. Utilizing behavioral strategies such as positive reinforcement for engaging in their routine and visual schedules can help reinforce bedtime expectations and promote compliance. 

Understanding the developmental milestones of sleep in children aged 2-6 allows caregivers to implement evidence-based strategies that support healthy sleep habits and promote optimal child development. By fostering a supportive sleep environment, implementing consistent bedtime routines, and addressing sleep-related challenges proactively, parents can lay the foundation for lifelong healthy sleep habits in their children. As a BCBA, I encourage caregivers to approach sleep management with patience, consistency, and a proactive mindset, recognizing that each child's sleep journey is unique and may require individualized support and intervention every now and then! Check out some resources in our Caregiver Corner for more tips on teaching sleep as a skill and setting up your child's bedroom for success.
