First, the ground rules
Sleep training means helping a baby learn to fall asleep (and back to sleep) with less help from parents. It is not recommended before 4–6 months of age, it should never be used to withhold food or comfort, and safe sleep comes first: always back to sleep, a firm flat mattress, and an empty crib.
Whatever the method, consistency for about two weeks matters more than perfection. And a quick check-in with your pediatrician before starting is a sensible step, especially if your baby was born early or has any medical condition.
The main methods
- Graduated extinction (Ferber) — put baby down awake, then wait before responding with increasingly longer intervals (for example 3, 5, 10 minutes). Visits are brief and reassuring, not feedings.
- Extinction (often called "cry it out") — put baby down and do not respond until morning (with exceptions for illness or a genuinely missed feed). Fastest results, hardest on parents' ears.
- Chair method — sit by the crib, move the chair further away every few nights until out of the room. Slow but gentle, and very hands-on.
- Gentle fading / pick-up-put-down — soothe without picking up (or pick up and put down again), gradually doing less each night. Slowest, but no crying beyond brief protests.

Your baby's age and temperament, your own tolerance for crying, and how much help you have all matter. There is no single "best" method — there is a method that fits your family. What the research consistently shows is that a consistent approach beats a perfect one that you abandon after three nights.
Common pitfalls
- Starting during a regression or illness — nap transitions, growth spurts, and illness are the worst moments to start; wait for a stable week.
- Mixing methods — switching every few nights teaches the baby that persistence wins. Pick one plan for two weeks.
- Skipping wake windows — an overtired baby trains worse. Check the age-appropriate wake window before bedtime.
- Giving up too early — nights 3–5 are often the loudest protest before the turn; plan for two weeks, not two days.
What tracking has to do with it
Sleep training works best when you can see the baseline. Logging bedtimes, night wakes, and nap timing lets you pick a calm week, notice whether wakes are actually decreasing, and show your pediatrician real data instead of "it feels worse."
Tips
Protect the wake window
An overtired baby resists sleep training the most. Use the age-appropriate wake window and a consistent bedtime.
One plan, two weeks
Pick a method and commit for 14 nights. Nights 3–5 often look worse before they look better.
Agree with your partner
Both caregivers must respond the same way at 2 a.m., or the training teaches the wrong lesson.
Skip during regression
Nap transitions, growth spurts, or illness are not the time to start. Wait for a stable week.
