How To Sleep Train 20 Month Old | Bedtime That Sticks

Sleep training at 20 months is less about letting a toddler cry and more about teaching one clear pattern: bedtime happens the same way each night, and sleep happens in the same place. If your evenings have turned into rocking, extra books, lost water cups, you do not need a fancy method. You need a schedule that fits your child, a short routine they can predict, and calm follow-through when they test the limit.

What Sleep Training Means At 20 Months

For a 20-month-old, sleep training means learning to fall asleep without a long chain of parent-led steps that must be repeated after each wake-up. If your child falls asleep only on your chest, in motion, or with you next to the crib, they often want that same setup again later in the night. The job is making bedtime plain, calm, and repeatable.

Sleep Training A 20 Month Old Without Long Bedtime Battles

Start With The Schedule

Before you change bedtime behavior, check total sleep. Children ages 1 to 2 usually need around 11 to 14 hours of sleep in a day, including naps, based on AAP sleep-hour guidance. If your toddler naps late, sleeps in, or gets too much daytime sleep, bedtime can drift later.

Many 20-month-olds do well with one midday nap and bedtime somewhere around 7:00 to 8:30 p.m. Wake time, nap time, and bedtime should stay in a close window each day.

Build A Short Wind-Down

A good routine at this age takes about 20 to 30 minutes. Bath, pajamas, teeth, one or two books, a short cuddle, lights low, then bed. The American Academy of Pediatrics bedtime tips also point parents toward quiet, repeatable steps instead of lively play right before sleep.

Keep the routine in the same order every night. If the order stays fixed, the room feels calmer and your child knows what comes next.

Pick The Rules Before Night One

Choose your rules in advance so you are not making tired decisions. Good rules are simple:

• One bedtime.
• One routine.
• One sleep space.
• One brief goodnight phrase.
• One response plan for calling out or getting up.

Also decide what will not change after lights out. Maybe your child keeps one stuffed toy and one cup of water nearby. Maybe there is one short check-in after a minute or two, then longer gaps. The exact method matters less than your consistency.

A Seven-Night Reset For Bedtime

This reset works for many toddlers because it trims the bedtime routine without turning night one into a huge shock.

1. Night 1: Do the routine, place your child in bed awake, say the same goodnight line, and leave.
2. Night 2: If your toddler cries or calls out, wait a short beat, then return for a calm check under 30 seconds.
3. Night 3: Stretch the gap between checks a little. No new books, snacks, or rocking.
4. Night 4: If your toddler stands or sits up, lay them back down once, say goodnight, and leave again.
5. Night 5: Treat night wakes the same way you treated bedtime.
6. Night 6: Cut extra reassurance. Your child now knows the script.
7. Night 7: Stay steady. This is when many toddlers stop trying every trick.

Your child may cry more on nights two to four. That does not always mean the plan is wrong. It often means your toddler has noticed that the old bedtime pattern changed.

Bedtime snag	Likely reason	What to do tonight
Takes over 30 minutes to fall asleep	Nap runs late or bedtime is too early	Trim nap length or move bedtime 15 minutes later for three nights
Cries as soon as lights go out	Routine ends too fast or goodnight keeps changing	Use the same final two steps and the same line every night
Calls for water again and again	Delay tactic	Offer one last drink before bed and leave a small cup nearby
Needs a parent in the room	Sleep-onset habit	Use a chair near the bed, then move it farther away every two nights
Wakes soon after bedtime	Not fully asleep when placed in bed	Put your child down awake, not asleep in your arms
Gets silly and wired at bedtime	Overtired or too much late play	Start the routine 15 minutes earlier and dim lights sooner
Wakes at 5 a.m.	Room is bright or the wake has turned into a habit	Darken the room and use the same calm response until your set wake time

What To Do When They Cry, Call Out, Or Get Up

Your response should stay calm and boring. Go in only if you planned to. Keep the room dim. Keep your words short. Do not turn bedtime into a second play period.

If your child has moved to a toddler bed and keeps getting out, walk them back with as little chatter as possible. You are teaching the same rule each time: bed is where sleep happens. The NHS sleep advice for young children makes the same point in plain terms: use a calm bedtime routine, avoid screens before bed, and keep taking a child back to bed with little fuss.

• Use one bedtime phrase such as “It’s sleep time. I love you. Goodnight.”
• Do not negotiate after lights out.
• Do not add new habits you cannot keep for the next month.
• Do not rush in for every sound. Many toddlers grumble, sit up, then settle.

If full check-ins make your toddler madder, a chair method can work better. Sit quietly near the bed for a few nights. Then move the chair a little farther away every two nights until you are out of the room.

Nap Timing, Food, And Screens

At 20 months, daytime sleep still matters. One nap often lands best after lunch. If the nap starts late in the afternoon, bedtime can blow up. If the nap is dropped too soon, your child can hit bedtime overtired and frantic.

A small snack before teeth can help if hunger is part of the bedtime loop. Keep it plain and easy: yogurt, milk, toast, banana, or cereal. Also skip tablets and phones in the hour before lights out. Bright screens can keep toddlers alert when you want the room winding down.

If this happens	Try this next	Skip this
Your toddler screams when you leave	Brief timed check-ins or a chair beside the bed	Starting a brand-new routine every night
Your toddler keeps asking for one more thing	Offer all final choices before lights out	Extra books, snacks, or songs after goodnight
Night wakes last over 20 minutes	Use the same response as bedtime	Rocking to sleep after every wake
Bedtime is getting later each night	Set a fixed wake time and protect nap timing	Letting morning sleep drift later and later
Your child seems wired after dinner	Quiet play, dim lights, low noise	Roughhousing right before bed

When Sleep Training Slows Down

Illness, teething pain, travel, a new sibling, daycare changes, or moving from crib to bed can throw off a good routine. If your child gets sick, meet the need, then go back to your normal bedtime pattern once they feel better. Trouble starts when sick-night habits stay long after the fever, cough, or pain is gone.

When To Call Your Child’s Doctor

Call your child’s doctor if your toddler snores hard, gasps, pauses in breathing, vomits at night, scratches all night from itchy skin, wakes in pain, or sleep has crashed after a fever or ear symptoms. Also call if your child is getting far less sleep than usual for more than two weeks, or daytime mood and energy have changed a lot.

If your gut says something feels off, trust it. A child with pain, breathing trouble, or repeated illness needs a different plan.

A Simple Bedtime Script

You do not need perfect words. You need steady words. Try this:

“Bath, books, bed. Now it is sleep time. Bunny stays with you. Water is here. I love you. Goodnight.”

Then leave. If your toddler calls out, repeat the short version. If they get up, return them with the same line. No debate. After a few nights, many toddlers stop spending so much energy on a routine that no longer changes.

That is the real goal of sleep training at 20 months: not a silent night on day one, but a bedtime your child can read, trust, and settle into night after night.
