How Sleep Needs Evolve as Kids Grow: A Guide for Moms of Babies and Toddlers
As a mom of a baby or young toddler, you’re probably juggling naps, bedtimes, and those precious moments of rest, for both you and your little one. But have you ever wondered how your child’s sleep needs will shift as they grow?
Understanding these changes can help you support your child’s sleep through timing, environment, and responsive methods, setting the foundation for healthy sleep habits for years to come. Let’s talk about how sleep evolves from infancy through the early school years, with practical tips tailored to you, the moms of babies and toddlers.
Infant Sleep Needs (0-12 Months)
In the newborn stage, your baby’s sleep is beautifully chaotic with anywhere from 14 to 17 hours a day, spread across multiple naps (5+) and nighttime stretches. Their internal clock (circadian rhythm) is still developing, so sleep is less predictable, and bedtimes aren’t set in stone. By around 3–4 months, you might notice your baby starting to consolidate sleep into longer nighttime stretches, with 3-4 naps during the day, with slightly longer wake windows.
What You Can Do Now for Newborns and Infants Sleep:
• Timing: in the newborn stage, watch for sleepy cues like yawning, eye-rubbing, or fussiness to avoid overtiredness. As your baby gets beyond the newborn stage sleepy cues may become less reliable and you’ll be using wake windows more reliably than the sleep cues! Aim for age-appropriate wake windows (e.g., 60–90 minutes for newborns, stretching to 2–3 hours by 6 months) to prevent overtiredness.
• Environment: Create a sleep-friendly space: dark, cool (68–72°F), with white noise.
• Responsive Methods: Respond to your baby’s needs with whatever soothing techniques work best for your and your baby, like rocking, shushing, or patting, to calm them and help them feel secure as they learn to fall asleep.
Wake windows change rapidly in the first year of life, and it can feel like you’re changing their schedule every other week at times. As a sleep consultant, part of my job is to remind moms that this stage is about laying the groundwork. By establishing consistent routines now, you’re helping your baby develop skills that will serve them as they grow.
Toddler sleep needs (1-3 Years):
As your baby becomes a toddler, their sleep needs drop to about 11-14 hours per day, including 1-2 naps. They are able to stay awake longer between sleep periods. You might notice it takes them longer to fall asleep, especially as their little minds become more active, processing language, emotions, and new experiences.
Around 12–18 months, many toddlers drop from two naps to one, often lasting 1.5-3 hours in the early afternoon. Between ages 3-5, some kids may start phasing out naps entirely, which can make bedtime feel like a marathon as they fight sleep or stall with requests for “one more story.”
What You Can Do Now for Toddler Sleep:
• Timing: Stick to a consistent bedtime routine (e.g., bath, book, cuddle) to signal it’s time to wind down. If bedtime is getting later, ensure wake windows align with their age (4-6 hours for toddlers).
• Environment: Keep the sleep space calm and distraction-free. Blackout curtains are a game-changer for toddlers who might be tempted to stay awake with even a sliver of daylight.
• Responsive Methods: Be patient with bedtime resistance. Offer choices within boundaries (e.g., “Do you want the blue pajamas or the green ones?”) to give them a sense of control while keeping the routine predictable.
Toddlers thrive on consistency. They may constantly test the boundaries but consistency is what they need. Even as their sleep needs shift, a reliable routine helps them feel secure, making it easier to navigate those longer stretches before bedtime.
Preschool and Early School Age Sleep Needs (3-6 Years): Later Bedtimes and School Wake-Ups
By the preschool years, kids need about 10-13 hours of sleep, often with no naps by age 4 or 5. Bedtimes typically shift later, landing between 7:30-9:00 PM, as kids become more active and engaged during the day. Falling asleep can take longer (sometimes 20-30 minutes) as their imaginations run wild or they process the day’s events.
Once school starts, wake-up times often become non-negotiable, driven by school schedules (think 6:30-7:30 AM). Without a nap to bridge the gap, overtiredness can creep in, leading to meltdowns or difficulty settling at night, so use earlier bedtimes if needed.
What You Can Do Now (and Prepare For):
• Timing: Gradually adjust bedtime earlier as school approaches to align with morning wake-ups. For example, if your 5-year-old needs 11 hours of sleep and must wake at 7:00 AM, aim for an 8:00 PM bedtime.
• Environment: Maintain a calming bedroom setup. Consider a dim nightlight for kids who develop nighttime fears, but avoid screens if you notice they struggle falling asleep, at least an hour before bed, as blue light can disrupt melatonin production.
• Responsive Methods: Use storytelling or guided relaxation to help active minds settle. For school-age kids, talk through their day to ease worries that might keep them awake.
As your child approaches school age, the habits you’re building now, consistent routines, a sleep-friendly environment, and responsive soothing, will make these transitions smoother.
