The 2-Year-Old Sleep Regression: What You Should Know

Sleep regression commonly appears near age 2, when a toddler who previously slept well begins to encounter sleep difficulties.

Though you may never have expected your newborn to sleep through the night, by toddlerhood you’ve likely developed a fairly dependable bedtime and sleep pattern.

Whether it’s a bath, a book, or a lullaby that signals your child to settle down, you’ve typically perfected the bedtime ritual that suits your household by the time they turn 2.

All the effort you invested in establishing a calm routine makes it especially disheartening when your child suddenly struggles with sleep after months of consistent bedtimes.

If you have a roughly 2-year-old who has recently stopped sleeping as before — resisting bedtime, waking repeatedly during the night, or getting up for the day far too early — your child is likely experiencing the 2-year-old sleep regression.

Read on to learn what it is, how long it might last, what triggers it, and what steps you can take to help it resolve as soon as possible.

What is the 2-year-old sleep regression?

Sleep regressions can occur at various ages, such as 4 months, 8 months, 18 months, and around 2 years.

When your toddler has sleep troubles, multiple factors may be involved, but a regression can be identified by its timing, duration, and whether other issues might be contributing to the sleep disruption.

The 2-year-old sleep regression is a short span during which a 2-year-old who had been sleeping well begins to resist bedtime, wake through the night, or rise too early in the morning.

Although this regression can be particularly trying for caregivers, it’s important to recognize that it’s normal and temporary. A small 2005 study reported that 19 percent of 2-year-olds experienced sleep problems, but these tended to improve over time.

How long does the 2-year-old sleep regression last?

Even a single night of poor sleep can leave you drained the next day, but remember that like other sleep regressions, the 2-year-old regression is not permanent.

If you respond consistently to nighttime behavior and remain patient, this phase will most likely resolve within 1 to 3 weeks.

Is it normal for a 2-year-old to go through sleep regression?

Yes — sleep regression at age 2 is fairly common. When it occurs, it’s natural to wonder what’s disrupting your established routine. While every child is different, there are several common reasons a toddler might experience this regression.

Developmental advances

As toddlers explore, they constantly acquire new abilities and skills. Sometimes, that burst of growth and learning can interfere with nighttime sleep.

At age 2, children undergo leaps in physical coordination, language, and social understanding, which can lead to tougher bedtimes and increased night wakings.

Separation anxiety

Although it may be brief, separation anxiety can still trouble toddlers. Your child might cling more, have trouble separating from a caregiver, or insist that a parent stay until they fall asleep.

Being overtired

Unlike most adults who fall asleep more easily when exhausted, children often exhibit the opposite behavior.

When a toddler keeps pushing bedtime later, they can become overstimulated from being overtired, making it harder for them to settle down and fall asleep.

Newfound independence

Alongside expanding skills, toddlers develop a stronger desire for independence. Whether insisting on dressing themselves or repeatedly climbing out of the crib, this drive for autonomy can create bedtime challenges.

Family changes

Major shifts in family life often occur around a child’s second birthday — for example, the arrival of a new sibling.

Welcoming a new baby is joyous but can prompt behavioral changes and sleep disruptions in older children, as can other significant life events.

Changes to nap schedule

Near age 2, some toddlers begin to give up their nap as their schedules become busier. With full days of outings and playdates, fitting in a midday nap can be difficult. Alterations to nap patterns almost always affect nighttime sleep.

If your child has dropped a nap, shortened daytime sleep, or resists daytime rest, you may notice impacts on their nighttime sleep as well.

Teething

Many toddlers are getting their 2-year molars, which can be uncomfortable or painful. Teething discomfort may interfere with their ability to sleep soundly through the night.

Fears

At 2, children are beginning to perceive the world in more complex ways, and with that can come new fears. An appropriate fear of darkness or imagined scary things may be behind sudden sleep problems.

How do I fix my 2-year-old’s sleep regression?

There are practical, straightforward steps you can take to start addressing this regression.

Ensure health and safety

Begin by confirming that your child’s basic needs are met and that they aren’t uncomfortable or in pain from illness or issues like teething.

Once you’ve ruled out health problems, address any environmental factors that could be causing bedtime difficulties.

If your toddler keeps climbing out of the crib, ensure the mattress is at its lowest position. Ideally, you’ve already lowered it once your child could pull to standing. When the lowest crib rail sits at or below your child’s nipple line while upright, it’s time to transition to a toddler bed.

The American Academy of Pediatrics suggests switching to a toddler bed when a child reaches 35 inches (89 centimeters) in height.

If your child is already in a toddler or full-size bed, make sure the room is childproof: anchor furniture, remove fragile or hazardous items, and follow other safety practices so your toddler can move safely at night.

If fear of the dark is an issue, consider adding a night-light or a small lamp to make the room feel more reassuring and comfortable.

Maintain routines

Next, examine daily routines to address any daytime or evening factors that might be disrupting sleep.

Try to keep a consistent nap (or “quiet time” if naps are resisted) and aim to put your child to bed at approximately the same time each night, following the same calming sequence before sleep.

Keep calm and consistent

After handling health, safety, the environment, and routines, you’ll need patience to respond consistently to nighttime issues until the regression resolves.

If your child repeatedly leaves their room, experts suggest calmly picking them up or guiding them back to bed each time without showing excessive emotion.

Alternatively, you might sit outside their door with a book or magazine and gently remind them to return to bed whenever they try to leave.

Although it can be tempting to forcefully put them back in bed repeatedly, allowing a child to play quietly in a childproofed room (with few stimulating toys) until they tire and settle can be a gentler, simpler way to handle bedtime resistance.

More tips

• Keep your bedtime routine simple and manageable. Emphasize calming activities that help your toddler wind down.
• Avoid screens for at least an hour before bed. Screen exposure is linked to later bedtimes and reduced sleep.
• If you co-parent, take turns handling bedtime responsibilities.
• Remember this phase is temporary.

Sleep needs for 2-year-olds

Although it may sometimes seem like your toddler could function on very little sleep, 2-year-olds still require a substantial amount each day. Children this age typically need between 11 and 14 hours of sleep within a 24-hour period, usually split between a daytime nap and nighttime rest.

If your toddler isn’t getting the recommended sleep, you’re likely to notice daytime behavior problems and difficulties with naps and bedtime due to overtiredness.

Takeaway

Although the 2-year-old sleep regression can be exasperating for parents, it’s developmentally normal and common for toddlers to go through this phase.

If your child suddenly resists bedtime, wakes frequently at night, or gets up extremely early, address any underlying issues and then stay consistent and patient while the regression passes.

With steady routines and calm persistence, this sleep disruption will most likely subside within a few weeks.
