Why 20 Month Olds Are Different

Big opinions, established patterns - gentle change is still possible

At 20 months, your toddler isn't a baby anymore. They have preferences, routines they've come to expect, and the verbal skills to tell you (loudly) when things aren't going their way. The patterns you've built together over the past 20 months—rocking, nursing, co-sleeping, your presence at bedtime—feel permanent. And after so many months, it's easy to wonder if the window for change has closed. It hasn't. 20 month olds are capable of learning new sleep patterns. They understand routines. They respond to consistency and connection. With the right approach—one that honors your toddler's temperament and your parenting values—meaningful change is absolutely possible. Betteroo creates that gentle, personalized path forward.

20 Month Sleep Support: Big Feelings, Strong Patterns, and a Gentle Path Forward

Your 20 month old has been developing their relationship with sleep for almost two years. At this age, the challenges are less about biology and more about the patterns and expectations you've built together—and gently reshaping them.

PATTERNS FEEL PERMANENT (BUT AREN'T) Whatever bedtime looks like in your home—rocking, nursing, lying together, your presence until they're asleep—has been reinforced hundreds of times. These patterns feel locked in. But toddlers are remarkably adaptable. With a consistent, loving approach, new patterns can emerge. It takes patience and the right method, but it happens.

YOUR TODDLER HAS OPINIONS NOW At 20 months, your little one has words (or almost-words), strong preferences, and the stamina to protest when things change. Bedtime resistance, stalling tactics ("more water," "one more book"), and loud protests are all developmentally normal. They're not signs that change is impossible—they're signs your toddler is doing their job of testing boundaries.

SCHEDULE IS STILL YOUR SECRET WEAPON Most sleep struggles at 20 months trace back to schedule. A nap that's too late pushes bedtime into battle territory. A nap that's too short creates an overtired mess by evening. Getting the timing right solves more than you'd expect.

ONE NAP IS DEFINITELY THE NORM By 20 months, your toddler should be solidly on one nap. If there's any two-nap situation lingering, that's likely contributing to night sleep issues.

TYPICAL SLEEP NEEDS AT 20 MONTHS

  • Total daily sleep: 12-14 hours (many average ~13)
  • Nighttime sleep: 10-12 hours
  • Daytime nap: 2-3 hours (1 nap)
  • Wake windows: ~5 hours before nap, 5-5.75 hours before bed
  • Bedtime sweet spot: 7:00-8:00pm

SAMPLE SCHEDULE (1 NAP) 7:00am wake → 12:00pm-2:00pm nap → 7:45pm bedtime

"IS IT TOO LATE?" — NO. This is the question we hear most from parents of 20 month olds. The answer is clear: it's not too late. Change may take a bit longer than it would have at 6 months. The protests may be louder. But your toddler is capable of learning new sleep patterns—and most families see real improvement in 2-3 weeks.

WHAT ACTUALLY HELPS AT 20 MONTHS Success at this age comes from three things: a schedule that's dialed in, a method that matches your toddler's temperament AND your comfort level, and the consistency to hold gentle boundaries through the adjustment period. Betteroo personalizes all of it—and gives you scripts for every scenario.

We'd been rocking our 20 month old to sleep every night—sometimes for an hour. I thought we'd missed our chance to change anything. Betteroo's gentle approach got her falling asleep on her own in 2 weeks. I didn't think it was possible at this age. It is.

From 4 night wakings to sleeping through. Our son had never slept more than 4 hours straight in his entire life. At 20 months, we finally tried Betteroo. Three weeks later, he sleeps 11 hours. I cry happy tears now instead of exhausted ones.

The bedtime battles were lasting over an hour. Every night was a negotiation. Betteroo helped us create a consistent routine with clear, loving boundaries. Now bedtime takes 15 minutes and everyone is calmer—including us.

I was so worried it was too late. That 20 months of co-sleeping meant we were stuck forever. Betteroo showed us a gentle path to her own crib, her own sleep. It took 3 weeks but she did it—and she's actually happier and more rested. So are we.

Your 20 Month Sleep Questions, Answered

Everything you need to know about supporting better sleep when patterns feel deeply established.

Not at all. This is one of the most common questions we get, and the answer is reassuring: 20 months is absolutely not too late. Your toddler's patterns may be more established than a younger baby's, and the adjustment may be louder, but toddlers at this age understand routines and respond beautifully to consistency and connection. Most families see meaningful improvement in 2-3 weeks with the right approach.

Most 20 month olds need 12-14 hours of total sleep, with many averaging around 13 hours. This typically breaks down to 10-12 hours at night plus 2-3 hours during the day (one midday nap). The bedtime sweet spot is usually between 7:00-8:00pm. Consistently getting less sleep can affect mood, behavior, and development.

Night waking at 20 months is almost always about patterns or schedule—not hunger or biological need. Common causes: sleep associations (needing you present to fall asleep means needing you present to fall BACK asleep), schedule issues (nap too late or too short), or habits that have been reinforced over time. Betteroo identifies which factors are at play and addresses them gently.

Early waking is one of the trickiest sleep challenges—and very common at this age. Usual causes: nap ending too late, nap too short (creating overtiredness), bedtime too early, or too much total daytime sleep. Sometimes it's environmental (light, noise). Betteroo's quiz identifies the root cause and adjusts your schedule accordingly.

There's no single "best" approach—it depends on your toddler's temperament and your comfort level. Options range from very gradual/gentle (you stay present and slowly reduce involvement over weeks) to more structured check-in methods. Betteroo's quiz matches you with the approach most likely to work for YOUR toddler and YOUR values. We never require cry-it-out.

Most families notice positive changes within 5-7 nights. Established patterns at 20 months may take a bit longer to fully shift—typically 2-3 weeks for consistent sleep through the night. Progress is usually steady once schedule and approach are aligned, even if there are some bumpy nights along the way.

Some frustration is normal when routines change—your toddler is communicating that this is different from what they expected. However, Betteroo offers multiple approaches from very gradual (minimal upset) to more structured methods. You choose what aligns with your parenting values. Our goal is always to minimize distress while still making progress toward better sleep for everyone.

Absolutely. This is one of the most common feelings parents have at this age—and one of the most incorrect. Patterns that have been reinforced for 20 months feel permanent, but they're not. Toddlers are remarkably adaptable. With a consistent, loving approach that matches their temperament, new patterns emerge.

Yes! Many families continue breastfeeding while improving sleep. By 20 months, most toddlers don't nutritionally need night feeds, but you can absolutely keep bedtime or morning nursing sessions. The key is gently separating feeding from the falling-asleep process. Betteroo helps you decide what to keep and how to make the transition.

Yes! Many Betteroo families have toddlers in daycare. The key is working WITH your daycare schedule rather than against it. Betteroo factors in daycare nap times and helps you adjust home sleep accordingly. Some inconsistency between settings is normal and won't derail progress as long as home routines stay consistent.

Absolutely. Betteroo is built on evidence-based sleep science reviewed by pediatric sleep experts. Research shows that helping toddlers develop healthy sleep patterns has no negative effects on attachment, behavior, or development. We offer multiple approaches—you choose what feels right for your family. We never require methods that don't align with your values.

Betteroo goes beyond generic advice. We provide a truly personalized experience that adapts to your 20 month old's specific situation—established patterns, temperament, daycare schedule, your parenting style—in real-time. Plus, we consider YOUR capacity too. It's like having a compassionate sleep consultant in your pocket—at a fraction of the cost.
