Just when you thought your toddler was sleeping through the night—bam! They start waking up again, refusing naps, or battling bedtime. This is called a sleep regression, and while it’s frustrating, it’s also normal. Understanding the causes and strategies can help you ride out this phase with more rest and less stress.
Dr. Jenna Thompson, Pediatric Sleep Specialist: “Sleep regressions are signs of growth. They usually align with major developmental leaps that temporarily disrupt sleep patterns.”

✔️ Common ages: 18 months and 2 years

Signs of Sleep Regression
✔️ Increased night wakings
✔️ Trouble falling asleep at bedtime
✔️ Shorter or skipped naps
✔️ Early morning wake-ups
How to Handle Toddler Sleep Regression
1. Stay Consistent
✔️ Stick to the same bedtime and nap routine
✔️ Use calming rituals like a warm bath, quiet book, or lullaby
2. Offer Reassurance, Not Reinforcement
✔️ Comfort them briefly if they wake up, but avoid creating new habits like co-sleeping (unless that’s your preference)
✔️ Be gentle but firm
3. Keep Daytime Active
✔️ Make sure your toddler is getting enough stimulation and physical activity during the day
✔️ Avoid overstimulation close to bedtime
4. Limit Screen Time
✔️ No screens 1–2 hours before bedtime to protect melatonin levels
Dr. Elise Grant, Family Sleep Consultant: “During regressions, toddlers crave connection and reassurance. A steady, loving presence helps ease them back into restful sleep.”
When to Seek Help
✔️ If sleep issues persist longer than 6 weeks
✔️ If your toddler shows signs of anxiety or extreme overtiredness
✔️ Talk to your pediatrician or a certified sleep consultant

Frequently Asked Questions
Can teething cause a toddler sleep regression at 18 months?
Yes, teething is a common trigger for sleep disruptions around 18 months when molars often come in. The discomfort can wake your toddler at night or make it harder to fall asleep. Offering appropriate pain relief and extra comfort during this time can help ease the regression.
Should I let my toddler cry it out during a sleep regression?
That depends on your parenting philosophy and what feels right for your family. During regressions, toddlers often need extra reassurance rather than sleep training. Many experts recommend offering brief comfort and connection while maintaining consistent boundaries, but every family's approach is valid.
How do I know if it's a sleep regression or a sleep association problem?
Sleep regressions are temporary and usually tied to developmental changes, lasting 2 to 6 weeks. Sleep association issues persist over time and involve needing the same condition to fall asleep every time, like rocking or nursing. If the problem continues beyond 6 weeks, it may be a habit rather than a regression.
Is it normal for my 2 year old to suddenly resist naps during a regression?
Absolutely. Nap resistance is one of the most common signs of sleep regression at age 2. Your toddler's brain is working overtime processing new skills and independence, making it hard to wind down. Keep offering quiet time even if they don't sleep, and maintain the routine to help them return to napping.
Can starting potty training trigger a toddler sleep regression?
Yes, any major change or new skill can disrupt sleep, and potty training is a big one. Your toddler may wake more often to use the potty or feel anxious about accidents. Consistency, patience, and reassurance during this transition will help their sleep stabilize again.
What's the best bedtime for a toddler going through sleep regression?
Aim for a bedtime between 7:00 and 8:00 PM, depending on when they wake in the morning. An earlier bedtime can actually help prevent overtiredness, which makes regressions worse. Watch for sleepy cues like rubbing eyes or fussiness, and adjust by 15 minute increments as needed.
Will my toddler's sleep regression affect their mood and behavior during the day?
Yes, poor sleep often leads to crankiness, clinginess, tantrums, and lower frustration tolerance. Your toddler is dealing with exhaustion on top of developmental stress. Offering extra patience, quiet activities, and earlier bedtimes can help balance their mood while the regression passes.
Can I still nurse my toddler to sleep during a regression without making it worse?
You can, but be mindful of creating new habits that may be hard to break later. If nursing to sleep works for your family and doesn't lead to frequent night wakings, it's fine to continue. Just ensure your toddler can also fall asleep with other soothing methods so you have flexibility.
