Is This a Sleep Regression? Signs, Stages & How to Get Through It

Your toddler was sleeping great. And then, seemingly overnight, they weren't.

Suddenly they're fighting bedtime, waking up multiple times a night, or refusing naps they used to take without complaint. You haven't changed anything. So what's going on?

It might be a sleep regression - and if it is, here's what you need to know.

🔑 Key takeaways

• Sleep regressions in toddlers are normal, temporary, and often tied to developmental leaps.
• The most common toddler regressions hit around 18 months and 2 years.
• Consistency and calm are your most powerful tools for getting through them.

What is a sleep regression? 

A sleep regression is a period - usually lasting 2-6 weeks - when a child who was previously sleeping well suddenly struggles to fall asleep, stay asleep, or both.

For toddlers ages 1-3, regressions are almost always linked to development. Language explosions, increased independence, big emotional growth, and major milestones like potty training or a new sibling can all disrupt sleep patterns that felt rock solid just days before.

It's not a step backward. It's a sign your child's brain is working hard.

Common signs of a toddler sleep regression

• Suddenly fighting naps or dropping them earlier than expected
• Taking much longer to fall asleep at bedtime
• Waking frequently through the night
• Early morning waking - much earlier than usual
• Increased clinginess or separation anxiety at sleep time
• More emotional or dysregulated behavior during the day

If several of these sound familiar and nothing in your routine has changed, a regression is likely what you're dealing with.

When do toddler sleep regressions happen? 

The two most common windows are:

18 months: This one tends to be intense. Your toddler is navigating a language explosion, growing independence, and some of the biggest separation anxiety of toddlerhood - all at once. Bedtime battles and night wakings are very common.

2 years: The 2-year regression often coincides with the transition out of the crib, potty training, a new sibling, or simply the emotional turbulence of being two. Big feelings during the day frequently spill into disrupted nights.

Some toddlers also experience a regression around 18-24 months when they begin dropping their afternoon nap. The transition is real and takes time.

How to get through it

 

Hold the routine

When sleep falls apart, the instinct is often to change things — earlier bedtime, longer nap, different approach. In most cases, the opposite is true.

Consistency is what toddlers need most during a regression. Stick to your usual bedtime routine as closely as possible. Predictable sequences - bath, books, song, lights out - signal to the nervous system that sleep is coming, even when the brain is buzzing with new development.

Respond with calm, not urgency

Night wakings feel urgent, especially when you're exhausted. But how you respond matters.

Keep your response brief, warm, and consistent. A reassuring hand on the back, a quiet "I'm here, it's sleep time," and a gentle exit. Lengthy interactions, screen time, or bringing your toddler into your bed - if that's not your norm - can inadvertently reinforce the waking.

Acknowledge the big feelings

Toddlers going through regressions are often emotionally flooded during the day too. Name what you see: "Bedtime feels hard right now. I get it."

Daytime connection and co-regulation - cuddles, play, one-on-one time - fill the emotional tank and often ease nighttime anxiety.

Adjust temporarily, not permanently

It's okay to offer a little more support during a regression - an extra book, sitting nearby until they settle - as long as you're conscious of slowly pulling back as things improve. The goal is to bridge the hard stretch without creating new sleep dependencies that outlast the regression itself.

How long will it last? 

Most toddler sleep regressions resolve within 2-6 weeks when parents stay consistent.

If sleep disruption continues beyond 6 weeks, or if it's significantly impacting your child's daytime functioning or your own wellbeing, it may be worth speaking with your pediatrician or a certified sleep consultant.

Bottom Line

Sleep regressions are hard - especially when you thought you were past the hard part.

But they are temporary, they are developmental, and they do end.

Hold your routine. Stay calm. Offer connection. And give it time.

A note for the exhausted parent

Toddler sleep regressions are one of those things that are hard to explain unless you're in the middle of one. If you're running on empty right now, that's completely valid.

You're not failing. Your child is growing. And this will pass.
