Getting a toddler to sleep comes down to three things: a consistent routine, the right environment, and a gradual approach to teaching them to fall asleep independently. Toddlers aged 1 to 2 need 11 to 14 hours of total sleep per day (including naps), and preschoolers aged 3 to 5 need 10 to 13 hours. If your child is fighting bedtime, waking through the night, or both, there are proven strategies that work within a few weeks.
Build a Predictable Bedtime Routine
A consistent bedtime routine is the single most effective tool for toddler sleep. A panel of 59 UK sleep experts identified six components of an effective routine: brushing teeth, going to bed at the same time each night, reading a book, avoiding food and drinks close to bedtime, turning off screens, and doing a calming activity like a bath or quiet conversation.
The key word is “predictable.” Toddlers feel safer when they know what comes next. A solid routine might look like this: bath, pajamas, brush teeth, two books, lights out. Keep the whole sequence to about 20 to 30 minutes. Do it in the same order every night, and start it at the same time. If bedtime is 7:30, the routine begins at 7:00. Your toddler’s internal clock will start to sync with the pattern within days.
Set Up the Right Sleep Environment
The bedroom itself matters more than most parents realize. Keep the room cool, ideally between 16 and 20°C (about 61 to 68°F). Make it as dark as possible. A small, warm-toned night light is fine if your child is afraid of the dark, but avoid anything bright or blue-toned. White noise machines can help mask household sounds, especially if you have older kids or thin walls.
Remove anything stimulating from the sleep space. That means no tablets, no TV, and no toys that light up or make noise. The bedroom should signal one thing: sleep.
Turn Off Screens Before Bed
Screen use before bed increases poor sleep quality by about 33% compared to no screen use. The light from phones, tablets, and TVs suppresses the body’s natural sleep signals, and the content itself keeps a toddler’s brain wired and alert. Power down all screens at least 30 to 60 minutes before bedtime. Replace that window with the calming activities in your routine.
Teach Independent Sleep With Gradual Withdrawal
If your toddler can only fall asleep while being held, rocked, or lying next to you, they’ll need you again every time they wake in the night. The goal is to gently teach them to fall asleep on their own. One of the most parent-friendly methods for toddlers is called “camping out,” and it typically takes one to three weeks.
Here’s how it works. Place a chair or mattress next to your toddler’s crib or bed. Sit or lie there and pat or stroke them until they fall asleep, then leave. After about three nights, stop the patting and just stay present. Then, every few nights, move your chair a little farther from the bed, about a foot at a time, until you’re outside the doorway.
If your child wakes during the night, return to whatever position you’re currently at in the process. Keep interactions brief and boring. Speak softly (“Shh, it’s sleep time”), avoid eye contact, and don’t turn on lights. If your toddler gets truly upset, pick them up for a quick cuddle, then settle them back down. The gradual pace is what makes this approach work: your child learns to sleep independently without feeling abandoned.
Handle Night Wakings Calmly
Toddlers wake during the night. That’s normal. What matters is how you respond, because your response teaches them what to expect. When your child cries or calls out, check on them, but keep visits to about one minute. Stay calm, say something brief and reassuring, and leave. Don’t start a conversation, offer snacks, or bring them to your bed (unless that’s a deliberate choice you’re comfortable with long-term).
Some toddlers settle faster with frequent check-ins. Others get more riled up each time you appear. Pay attention to your child’s pattern and adjust. The visits exist to reassure both of you, not to entertain or re-engage your toddler.
What Diet Has to Do With Sleep
What your toddler eats during the day shows up at night. A study of 2-year-olds found that children with high intake of soft drinks, snacks, and fast food had 37% higher odds of inadequate sleep and 34% higher odds of waking during the night. On the flip side, moderate to high vegetable intake was linked to fewer night wakings.
One surprising finding: high dairy intake (milk, cheese, yogurt) was associated with more night waking, not less. This doesn’t mean you should cut dairy, but if your toddler is drinking large amounts of milk close to bedtime, it could contribute to disrupted sleep through a full bladder or digestive discomfort. A light, balanced dinner with vegetables and complex carbohydrates, finished at least an hour before bed, sets the stage for better rest.
Sleep Regressions Are Temporary
If your toddler was sleeping well and suddenly isn’t, you’re likely in a sleep regression. These commonly hit around 18 months, 2 years, and 3 years, and each one has different triggers.
The 18-month regression is often the roughest. Separation anxiety peaks between 15 and 18 months, first molars are breaking through, your child is learning to walk and climb, their brain is processing a language explosion, and many toddlers are also dropping from two naps to one. All of that happening at once is a recipe for terrible sleep.
At 2 years, the regression is driven by independence and boundary-testing. Your toddler now has the language skills to stall bedtime with requests for “one more story” or “water” or “potty.” Moving to a toddler bed too early, the arrival of a new sibling, or second-year molars (which come in between 23 and 33 months) can all pile on. This phase typically lasts 2 to 6 weeks.
By age 3, the issues shift to imagination and fear. Nightmares feel very real at this age, and many children develop a fear of the dark or of monsters. Starting preschool, dropping the afternoon nap, or any major life change can trigger the regression. The best response at every stage is the same: hold your routine steady, offer comfort, and avoid introducing new sleep habits (like co-sleeping or lying with them until they’re fully asleep) that you’ll need to undo later.
When to Switch From Crib to Bed
Many parents switch to a toddler bed too early, which can make sleep problems worse. A toddler in a bed they can leave freely has far more opportunities to resist bedtime. The American Academy of Pediatrics says a child has outgrown their crib when they’re taller than 35 inches or when the crib railing sits at the middle of their chest while standing.
The other clear sign is climbing out. If your toddler is regularly escaping the crib even with the mattress at its lowest setting, the crib has become a safety hazard and it’s time to transition. But if the crib is still containing them safely, there’s no rush. Look for signs of readiness beyond just physical size: the ability to fall asleep independently, sleeping through the night consistently, and following household rules. If your child is asking about a “big kid bed,” that interest can also signal they’re ready for the change.
Nap Transitions and Timing
Between 12 and 24 months, most toddlers shift from two naps to one. This transition can temporarily wreck nighttime sleep because your child is overtired by evening but not yet adjusted to the new schedule. Keep the single nap in the early afternoon (starting around 12:30 or 1:00) and cap it so it doesn’t push too close to bedtime. Most toddlers do well with a nap of 1.5 to 2 hours.
Around age 3 to 5, the afternoon nap starts to disappear entirely. This process is often gradual: your child may nap some days but not others. If your toddler is napping well but fighting bedtime for over 30 minutes at night, the nap may be the culprit. Try shortening it before dropping it altogether, and move bedtime earlier on no-nap days to prevent overtiredness.
