I need to talk to the mom reading this at 4 a.m. with a nine-month-old on her chest.

The one who keeps thinking she missed her window. The one who googles “is it too late to sleep train” and gets a bunch of vague answers about how “it’s harder after six months” and “every baby is different” and “just do what feels right for your family.”

None of that is helpful. So let me be clear: It’s not too late. You didn’t miss anything. Your baby can absolutely learn to sleep independently at six, eight, ten, even twelve months old.

It’s just going to be spicier. Because your baby is no longer a confused little potato. They’re a sharp-eyed, opinionated tiny human who knows exactly what they want. And what they want is you, all night, forever.

Why Older Babies Are Harder (But Not Impossible)

A newborn doesn’t have preferences yet. They don’t know what a “routine” is. They don’t have enough memory to protest a change in the plan.

Your eight-month-old? They remember. They know that if they scream long enough, you’ll pick them up. They know that the boob or bottle comes when they cry at midnight. They’ve had months of practice refining their negotiation tactics.

So when you change the rules, the protest is louder. Longer. More dramatic. They might pull out moves you’ve never seen: standing in the crib, throwing the pacifier, rage-babbling at the door like a tiny Shakespeare villain delivering a monologue.

That’s not damage. That’s a baby who’s annoyed that the old system stopped working. It’s a tantrum, not trauma.

The Good News About Starting Late

Their bodies are ready. A six-month-old can physiologically sleep through the night without a feed. You’re not fighting biology. Just habits.

They learn patterns fast. Older babies love predictability. Once the new routine clicks, they settle into it quickly.

You skip the hardest newborn stuff. No setting alarms every three hours. No cluster-feeding chaos. No “is this gas or is my baby broken” guessing games.

You’re stepping straight into the age-appropriate version of the method. No tutorial mode required.

What Starting Looks Like at 6+ Months

Step one is the same regardless of age: set a morning anchor time (a fixed morning wake time that every nap and bedtime flows from). That’s your new non-negotiable. The time your baby wakes up every single day. Not “when they happen to stir.” A deliberate, consistent start.

Step two: age-appropriate wake windows (age-appropriate stretches of awake time between sleeps). At six months, that’s about 2.5 hours. At nine months, closer to 3 to 3.5 hours. Your baby can stay awake longer than you think. You’ve just never tested it because you were too busy nursing them to sleep every ninety minutes.

Step three: put them down awake. In the crib. And walk out. Yes, they will protest. Louder than a newborn would. With more conviction. Possibly while making sustained, accusatory eye contact.

It will pass. Usually within three to five days.

Let Go of “I Should Have Done This Sooner”

You did what you could with what you knew. Maybe the newborn stage was survival mode. Maybe you were recovering from birth. Maybe nobody told you this was an option. None of that matters now. What matters is: you’re here, you’re ready, and your baby can learn this.

My new book Mom Awakened has a full chapter dedicated to starting the method with an older baby. No judgment. No “you should have started earlier.” Just the exact steps, age-appropriate schedules, and what to expect when your spicy little human decides to test you. Coming soon.
