The first night, minute by minute

Most of the anxiety about Ferber lives in the first night. By the second night you know what the protocol feels like, and by the third you have the data. The first night is where parents quit, and almost always for one reason: they did not have the minute-by-minute in their head before they started. This guide is that minute-by-minute, plus the contingencies for the things that actually happen.

The waits, written out

Tonight you wait three minutes, then five, then ten, then ten, then ten, until your baby falls asleep. If your baby wakes later in the night, you do the whole sequence again from three.

Night	First wait	Second wait	Third wait	Then repeat
Night 1	3min	5min	10min	10min

After the third interval, the third value repeats until your baby falls asleep.

That is the protocol. Every other line in this guide is detail.

Before the routine

Eat something. Drink water. Use the bathroom. The first interval is the shortest at three minutes. The third is ten. You will not want to leave the hallway during a wait, so handle yourself before bedtime starts.

If you have a partner, decide who is doing the check-ins tonight. The other partner does not check in, no matter what. Switching produces inconsistent check-ins, which the baby reads as “if I cry the right way, a different adult comes.”

The routine

Run the bedtime routine you already have, in the order you already use it. Bath, lotion, pyjamas, feed, story, song, into the cot. Keep it under thirty minutes. Lights stay low from the start of the routine. White noise stays at the same level you would normally use, no louder.

The only change tonight is the very last step.

The drop-off

Put your baby down drowsy but awake. This is the most important sentence on this page.

What “drowsy but awake” looks like in practice: heavy eyes, a slow blink, a soft cry or grizzle, but they can still see you when you put them down. If they are fully asleep when they hit the mattress, wake them gently. Yes, intentionally. The point of the protocol is that they learn to fall asleep without you. They cannot learn that if they are already asleep when you walk out.

Walk out. Close the door if that is your normal. Do not look back from the hallway. Start the three-minute timer.

The first wait, three minutes

Your baby will probably cry. Probably loudly. Three minutes is going to feel like fifteen. Do not go in. Do not stand in the doorway. Go to a different room if you can hear them too clearly.

If your baby pauses for fifteen seconds and then cries again, the timer keeps running. The wait is the wait, not the wait minus the pause. The Sleep Foundation summary makes this point well: the consistency is what works.

When the timer hits zero, walk in.

The first check-in

Under one minute. Soft voice, brief pat, the same words every time. The words do not matter much, the consistency does. Most parents settle on something like “It’s okay. I love you. Time for sleep.” Some say nothing at all. Both work.

What you do not do during a check-in:

• Pick up.
• Turn on the light.
• Make eye contact for more than a second or two.
• Feed.
• Change a diaper unless it is genuinely soiled, which you will know.
• Apologise. The baby is not insulted, they are confused. Calm voice fixes that, sorry-tone does not.

Walk out. Start the five-minute timer.

The second wait, five minutes

This is usually quieter than the first. Your baby is figuring out the shape of the night. Some babies cry less, some cry harder, some get quiet for two minutes and then start again with new energy. All of that is within normal.

Five minutes ends. Walk in. Same check-in as before.

The third wait, ten minutes

Ten minutes is the longest first-night interval and the moment most parents describe as the hardest of the whole arc. You can feel the protocol working now. You can also feel every minute. This is the wait where parents quit.

Make it. The structure of the night needs the third wait to be the third wait. After this, the math gets easier: every interval until your baby falls asleep is also ten minutes.

Go in. Same check-in. Walk out. Ten more minutes.

After the third check-in

You repeat ten-minute waits and quick check-ins until your baby falls asleep. Most babies fall asleep within one or two more cycles. Some sleep within the first ten-minute wait after the third check-in.

When your baby is asleep, you stop. The night is not over, but the first sleep cycle has started.

The first night waking

Your baby will wake at least once tonight. Most do. When they do, you start the sequence over from three minutes. This is the part of Night 1 that catches people. Each waking gets the full Night 1 sequence: 3, then 5, then 10, then 10s.

If a waking is in the early morning, before about 5 a.m., still do the sequence. After 5 a.m. you can decide based on your usual wake-up time whether to treat it as a waking or as a slightly early start to the day. Your baby’s normal wake-up time is the rule.

What success looks like tonight

Most Night 1s look like this:

• Cry hard for the first ten to fifteen minutes.
• Cry medium through the third interval.
• Fall asleep within twenty minutes after the third check-in.
• Wake one to three more times during the night.
• Each waking is shorter than the previous one.

If your night looked roughly like that, you are exactly on track. Tomorrow night the intervals lengthen and most of the time the total crying drops by half.

What to do tomorrow morning

Eat. Drink coffee. Notice that you survived. Glance at the Night 2-3 guide if you want a preview of where the arc usually dips, and skim the 7-night arc guide so you have the shape of the week in your head.

The hardest interval of the entire week was the ten-minute wait on Night 1. Everything from here is on a downward slope.

What the app does about Night 1

The Ferber app exists for tonight specifically. It runs the timer with a calm chime, logs each check-in, and shows you the next wait so you do not have to remember. If you are reading this and have not downloaded it yet, the download page has the App Store link. Ferber is on iPhone, and Night 1 is free.

If you are reading this on Night 1 itself, close this tab. You are ready. The protocol is exactly what is on this page. We will see you on Night 2.
