Sleep training a 6 month old: the schedule, the plan and the first week

If you only read one of these guides, read this one. Six months is the age where everything lines up: sleep cycles have matured, most babies can go a long stretch without a feed, separation anxiety has not peaked yet, and habits are still soft. It is the age the research used most, and the age most pediatricians point to.

The schedule first

At 6 months most babies are on three naps, moving to two somewhere between 6 and 8 months. Wake windows run about 2 to 3 hours, shortest in the morning and longest before bed. Total day sleep is around 3 to 3.5 hours. Bedtime lands between 6:30 and 8pm.

Get this right before night 1. A 6 month old put down at 8:30 after a late third nap will fight for an hour, and you will blame the method. Run your baby's wake up time through the wake window calculator and adjust for what you actually see.

Night feeds

Many 6 month olds still take one feed, often around 3 to 4am, and that is fine. Decide before you start whether tonight's plan includes a feed. If yes, feed in dim light at the first wake after a set time (say, after 2am), then back down awake, and treat every other wake with check-ins. If your pediatrician says your baby no longer needs it, taper it rather than stopping cold.

The plan, night by night

This uses the Ferber chart. The full guide has the reasoning; the timer runs it for you.

• Night 1. Routine, down awake, lights out. Waits of 3, 5, then 10 minutes, with a brief calm check-in at each. Expect 30 to 60 minutes of protest at bedtime and one or two long wakes.
• Night 2. Waits of 5, 10, then 12. Often a little better than night 1.
• Night 3. Waits of 10, 12, then 15. This is the night many babies protest hardest. It is the extinction burst, not a sign of failure.
• Night 4. Waits of 12, 15, then 17. For most babies, the first clearly good night.
• Nights 5 to 7. Waits of 15 to 30. Bedtime settles in under 15 minutes, wakes drop to the feed if there is one.

Use touch check-ins (hand on chest, quiet phrase) for the first two nights and voice from the door after that. If check-ins clearly make your baby more upset, switch to voice sooner or lengthen the waits. The Sleep Sanity ladder (5, 15, 30, then every 15, the same every night) is an alternative if you find the changing chart hard to track.

What the first week usually looks like

Logged across many families, the pattern is remarkably consistent: a hard night 1, a slightly better night 2, a worse night 3 or 4, then a sharp improvement. Total crying roughly halves every couple of nights. By night 7 most 6 month olds fall asleep within 10 to 15 minutes and wake once or not at all. Naps lag by a week or two and then catch up. What a sleep score means shows what that curve looks like as a number.

What goes wrong at 6 months

• The third nap. If it runs past 5pm, bedtime slides and the night suffers. Cap it at 30 to 45 minutes, or drop it and move bedtime earlier.
• Rolling and sitting. New skills get practised in the crib at 2am. Give plenty of floor time by day, and resist the urge to lay them back down every time.
• Teething. Real, but usually a day or two. Pause for pain, not for drool.
• Inconsistency between parents. Agree the intervals and the feed rule in daylight. Shared logging on both phones removes most of the 3am arguments.

If nothing has improved after seven consistent nights, work through the reasons it is not working before changing method.

FAQ

Is 6 months a good age to sleep train?

It is the best age for most babies. Sleep cycles have matured, most babies can go a long stretch without a feed, separation anxiety has not peaked, and habits are still easy to change. Most of the research used babies around this age.

What is a good sleep schedule for a 6 month old?

Wake windows of about 2 to 3 hours, three naps moving to two, around 3 to 3.5 hours of day sleep, and bedtime between 6:30 and 8pm. Keep the last nap from running past 5pm.

Does a 6 month old still need a night feed?

Many do, usually one. Ask your pediatrician. You can sleep train with a feed kept in: feed at the first wake after a set time, put down awake, and use check-ins for every other wake.

How long does sleep training take at 6 months?

Typically three to seven nights for bedtime and night wakes, with naps improving over the following one to two weeks. Night 3 or 4 is often the hardest.

Can I use the Ferber method at 6 months?

Yes, this is the age the chart was designed for. Start at 3, 5 and 10 minutes on night 1 and lengthen each night, with brief calm check-ins.
