When Should You Switch Your Toddler to One Nap a Day? (Here’s What I’m Doing with My Own Toddler)

Babies can be so confusing, right Valentina? (She's feeding her twins here. Poor gal never gets a break.)

If you’re wondering when to transition your toddler to one nap a day, let me share what’s happening with my 20-month-old, Valentina. Every child is different, but maybe our journey will resonate with you—or at least give you a place to start.

The Typical Timeline for Nap Transitions

Most toddlers switch from two naps to one somewhere between 15 and 18 months, though the range can stretch from 12 to 21 months. Since my kids have always leaned toward higher sleep needs, it didn’t surprise me that Valentina hasn’t fully switched yet.

But even though most kids follow this general timeline, every toddler’s journey is unique. And like most nap transitions, the process is rarely smooth or linear (because, of course, toddlers love to keep us guessing).

Why Valentina Hasn’t Switched Yet

Two weeks ago, we were at the beach, and Valentina thrived on a one-nap-a-day schedule—probably because she had the excitement of siblings and cousins to keep her busy. I thought, This is it! She’s ready!

But as soon as we came home, everything changed. Without all the stimulation, mornings felt so long for her. By mid-morning, she was cranky, exhausted, and miserable—making it clear that pushing her to one nap wasn’t the right move just yet.

We’ve even had a split night (you know, those nights when your toddler wakes up at 2 a.m., ready to party). That’s usually a sign of too much daytime sleep, which is why I initially wondered if maybe she should go to one nap a day. But the resulting morning crankiness made it clear that this wasn't quite right.

But… here’s the catch. I can hear her from my office after her first nap, and she’s cranky when I wake her up. It’s no fun for anyone, and it’s got me thinking: could tweaking her nap schedule help?

My Nap Transition Strategy

Here’s what I’m trying with Valentina—and what I recommend to parents who are navigating this tricky transition:

1. Move the First Nap Earlier This one is key. The first nap doesn’t have to happen when your toddler looks tired. In fact, they shouldn’t be very tired—it’s better if they’re just starting to yawn or slow down.

For example, we’ve been putting Valentina down around 9 a.m., but I’m moving it to 8:30 a.m. That feels early, but most days I start to see yawns by then. The goal here is to put her down when she's just a little bit tired. Which can feel strange!  

2. Cap the Morning Nap If you’re still doing two naps, try capping the first nap to starting at 90 minutes and reducing by 15 minute increments until you find a time that works. As your child grows, you'll have to keep shortening the time. For Valentina, I’ve been letting her sleep 60-75 minutes., but I’m starting to think that’s too long for her now. Every child is different, so experiment with timing to see what works for yours.

3. Adjust the Second Nap Once the first nap is shortened, shift the second nap slightly later, but not so late that it interferes with bedtime. For most toddlers, the sweet spot is around 1–2:00 p.m., but don’t let the nap go past 4 p.m.

4. Be Flexible Here’s a big takeaway: your toddler doesn’t have to follow the same nap schedule every day. At daycare, most toddlers take just one nap because that’s the schedule. At home, you can keep two naps on the table for days when they're looking tired before mid-morning.

This kind of flexibility might feel chaotic, but it’s normal during transitions. You’ll know your child is ready to drop to one nap completely when they start consistently skipping one of the naps—usually the afternoon one.

Signs Your Toddler is Ready for One Nap

Here’s what to look for:

• Your toddler consistently skips one nap (usually the second one) for multiple days in a row.
• They stay happy and energetic until late morning.
  
  

​When these signs show up, start gradually moving the first nap later (and shorter) until your little one is taking one (longer) midday nap.

Nap Transition Tips

• If your toddler skips the morning nap, try pushing it no later than 10 a.m., and cap it at one hour or less.
• Keep wake-up time consistent—aim for 7 a.m. to set the tone for the day.
• Remember, nap transitions are messy, and it’s okay if things feel imperfect for a while.

You’re Not Alone

Nap transitions—from 3-to-2, 2-to-1, or even 1-to-0—are some of the toughest parts of baby sleep. If you feel stuck or overwhelmed, don’t stress. It’s normal! And if you’d like personalized help, schedule a free consult—we’ll create a plan tailored to your little one’s needs.

Parenting is a journey, and nap transitions are just one of the many milestones. You’ve got this!
