In most cases, yes, as soon as your pediatrician confirms your baby is ready. Work from corrected age, which counts from the due date rather than the birth date: gentle habit-building can start at around 10–12 weeks corrected, and more complete sleep training at around 4–6 months corrected, as long as weight gain is steady and any medical issues are stable. Your custom plan sets how night feeds are handled according to your baby’s age. 

**Up at 3 a.m. and searching?** Tomorrow night does not have to look like tonight. Actually Sleeping writes a plan for your baby, coaches you intensively before night one so you start out confident, and checks in 1:1 every day until your baby sleeps through, backed by a full-refund guarantee.

_About the scope of this guide: Dr. Sam is a Doctor of Pharmacy and a Pennsylvania-licensed pharmacist. For a baby born early, readiness, feeding and every medical question are matters for your pediatrician or neonatal follow-up team._ 

## What corrected age is and why it counts 

Corrected (adjusted) age means your baby’s age since birth, minus the number of weeks they were born early (40 minus the gestational age at birth). A 6-month-old who arrived 8 weeks early is roughly 4 months corrected. The AAP advises using corrected age through the first 2 years when assessing development, so it is sensible to apply it to wake windows, nap counts and sleep expectations as well.  
| Corrected age | What you can realistically expect | 
|---|---|
| From before the due date to about 10 weeks | Feeding on your team’s schedule, safe sleep, cues for day and night. No training. | 
| 10–16 weeks | A consistent routine, practising putting your baby down awake, feeds kept as instructed | 
| 4–6 months | Falling asleep independently; night feeds set in the custom plan | 
| 6 months onward | Full sleep training; night weaning once cleared | 
 

## Start with these questions for your pediatrician  
- Is my baby’s weight gain on track along their own growth curve? 
- How many night feeds does my baby still need, and can I stop waking them for feeds? 
- Does fortified milk or a special formula schedule affect the nights? 
- Are reflux, breathing or oxygen needs, or a history of apnea, stable enough for a sleep plan? 
- Is there any reason not to give my baby a few minutes to settle? 
 

Babies who arrive early are fully able to learn good sleep. Actually Sleeping bases plans on corrected age and works around your pediatrician’s feeding instructions, so the plan suits your baby instead of an average baby born at term. 

## How NICU graduates differ  
- **Feeding stays the priority for longer.** Some preemies need feeds on a schedule, overnight included, well beyond the age a term baby would. Do not stretch or drop a feed without clearance. 
- **At home, sleep is on the back.** In the NICU, babies are sometimes laid on their stomach or side while continuously monitored. At home, NIH safe sleep guidance says every baby, preterm babies included, sleeps on their back until 1 year: firm and flat, an empty crib, no positioners or nests, no inclines. 
- **Medical equipment.** If your baby came home on oxygen or with a prescribed monitor, the plan has to be built together with the medical team. The AAP and NIH recommend against relying on heart, breathing or motion monitors to lower SIDS risk; they are no substitute for safe sleep. 
- **Light and noise.** After weeks in a bright unit full of alarms, some babies sleep through anything while others startle at the smallest sound. 
- **Reflux questions come up often.** Babies with reflux still sleep on their backs. Read [sleep training a baby with reflux](https://actuallysleeping.net/guides/sleep-training-a-baby-with-reflux/). 
- **Parents bring the NICU home too.** Being on high alert to every noise is an understandable response to what you have been through. A plan with set check-ins means you respond deliberately rather than on adrenaline. 
 

## Why off-the-shelf plans do not suit preemies 

Most sleep advice goes by age since birth and assumes a baby born at term. Followed to the letter, it can rush a preemie, or stretch feeds that a pediatrician wants maintained. A baby born early needs a plan based on corrected age, built around the pediatrician’s feeding instructions, and paced to their growth. 

## How we build a plan for a baby born early 

Actually Sleeping supports families from the newborn stage (foundations come first, and the 14-day guarantee clock begins at 10 weeks), using corrected age for babies born early. Dr. Sam writes every NICU graduate’s plan around the pediatrician’s feeding instructions: schedules follow corrected age, the approach begins with more parental presence and smaller steps, and the plan pauses during illness or if growth slows. You receive bootcamp-style coaching ahead of the first night and 1:1 check-ins every day afterwards. Parents of young babies share what it was like in [reviews from families of newborns to 3 month olds](https://actuallysleeping.net/reviews/newborn-0-3-months/). For twins born early, see the notes in [sleep training twins](https://actuallysleeping.net/guides/sleep-training-twins/). 

## When the plan should wait 

Weight gain that is faltering, a recent return to hospital, breathing that is not stable, a procedure coming up, or a pediatrician who says not yet. In any of these situations, the medical team’s timing takes priority. 

When you feel ready to tackle sleep with a baby born early, book a free consultation and have your pediatrician’s feeding instructions on hand.

## Common questions 

### Should I go by corrected age or actual age when sleep training a preemie?

Go by corrected age, counted from the due date. It is a better guide to sleep maturity, wake windows and nap needs, and the AAP advises using it through the first 2 years. 

### When will a premature baby sleep through the night?

That depends on growth and feeding needs. Your custom plan sets how night feeds are handled according to your baby’s age. For babies born early, the plan works from corrected age. 

### Can my preemie sleep on their tummy the way they did in the NICU?

No. In the NICU, tummy or side positioning happens with continuous monitoring. At home, the guidance from the AAP and NIH is the back for every sleep, babies born preterm included. 

### Is it harder to sleep train a NICU baby?

Not necessarily. It often begins later and proceeds in smaller steps, but NICU graduates whose weight gain is steady usually learn to sleep independently well.
