Check-ins, the part most parents get wrong
Last updated
The check-ins are what makes Ferber Ferber. Without them, the method is full extinction, also known as cry it out. With them done badly, the method is just a longer cry-it-out. This guide is about doing them well.
What a check-in is
A check-in is a brief visit to the cot during a wait. It is under one minute. It is calm, quiet, and predictable. The point is to reassure your baby that you are still here without becoming the thing they need to fall asleep.
The Cleveland Clinic summary puts it cleanly: a check-in is for reassurance, not soothing. Reassurance is what you say. Soothing is what makes them fall asleep. You want to do the first and not the second.
The exact structure
- Walk in.
- Speak softly. Same words every time.
- Optional brief touch: a pat on the back or a hand on the chest. Five seconds, not thirty.
- Walk out.
Total elapsed time, ideally between fifteen and forty-five seconds. Anything longer than a minute is too long.
What to say
Whatever you pick, pick it once and use it all week. Some examples that work:
- “It’s okay. I love you. Time for sleep.”
- “Shhh. Mommy is here. Sleep now.”
- “It’s bedtime. I love you.”
Tone matters more than words. Calm, low, neutral. Not cheerful, not apologetic, not stressed. Cheerful is exciting. Apologetic communicates that something is wrong. Stressed communicates the same.
Some parents say nothing at all. That works for some babies. If you try the silent check-in and your baby seems to settle faster, keep doing that. Consistency within the night matters more than which version you pick.
What not to do
Four things will undo most of the protocol’s benefit:
- Picking up. Even briefly. The baby learns that crying long enough produces a pickup, which means the next wait is louder, not quieter.
- Turning on the light. The light says “the night is over.” Tonight, the night is not over. The light comes on at your normal wake time, not in the middle of an interval.
- Feeding. Unless your pediatrician has signed off on a specific night feed, no feeding during a check-in. Adding a feed makes the feed the sleep aid, which means you will eventually have to do this all again to take the feed away.
- Lingering. A long check-in is a soothing session. The baby is learning that the visit can be extended. They will then extend it.
If you do one of these once, you have not ruined the week. Restart clean on the next interval. If you do one of them every interval, the week will not work.
How long should a check-in feel
Time check-ins by walking. Walk in, speak, optional pat, walk out. If you move at the speed you would walk to a kitchen for a glass of water, the check-in is the right length. If you find yourself swaying, sitting, or crouching, you are doing too much.
Some babies will calm visibly during the check-in and then start crying again as you walk out. That is not a sign you are doing it wrong. That is the protocol working. Walk out anyway.
When the check-in seems to make it worse
Some babies cry harder after a check-in than they were crying during the wait. This is uncommon but real, and it has a specific name in the literature: the “check-in surge.” It happens when the visit is just soothing enough to wake the baby up to a new level of upset.
If you see this on Night 1, run the protocol normally and see if it changes on Night 2. By Night 3 it almost always stops.
If it persists past Night 3, switch to silent check-ins: walk in, hand on the chest for five seconds, walk out, no words. Many “check-in surge” babies respond to that change immediately. The Huckleberry team recommends the same adjustment.
If it persists past Night 5, you can drop the touch and do a stand-and-look check-in: open the door, stand in view for five seconds, close the door. Some babies need only the visual confirmation. This is closer to full extinction than to standard Ferber, but it is a reasonable place to land for the small fraction of babies for whom the textbook check-in is genuinely counterproductive.
Two parents, one check-in
If two parents are at home, one of you does the check-ins for the night, the other does not. This is non-negotiable for the first three nights. Switching mid-night creates inconsistent check-ins and lengthens the arc.
You can swap nights. Some couples find night-on-night-off works. Some find that one parent has the temperament for the first three nights and the other takes over once the protocol is settled. Both are fine. What is not fine is two check-ins in one wait by two different people.
If you are co-parenting across two homes, run the same protocol in both. The intervals match, the check-in script matches, the bedtime window matches. The co-parenting guide covers this in more detail.
What the app does for check-ins
The app’s check-in button does two useful things. It logs the check-in, so you can see at the end of the week how many you did and how each night trended. And it prompts the next interval automatically, so you do not have to remember which wait comes after which.
The widget shows “Check in” when an interval is up and “Wait” while you are between checks. That is intentional. At 2 a.m. you do not want to be reading text. You want to know whether to walk to the room or stay where you are.
