Baby Sleep Schedule by Age: Complete Guide (0-12 Months)

Frequently Asked Questions

Is it normal for my baby to wake up every 2 hours at night?

Yes, this is completely normal for newborns up to 3 months old. Their tiny stomachs can only hold small amounts of milk, so they need to feed frequently around the clock. As your baby grows and their stomach capacity increases, those sleep stretches will naturally lengthen. Most babies start sleeping for longer periods between 3 and 6 months.

What is a wake window and why does it matter?

A wake window is the amount of time your baby can comfortably stay awake between naps. It includes feeding, diaper changes, play, and the bedtime routine. Following age-appropriate wake windows helps prevent overtiredness, which actually makes it harder for babies to fall asleep and stay asleep. As babies grow, their wake windows naturally get longer.

Should I wake my baby to keep them on schedule?

For newborns under 2 weeks or babies who aren't gaining weight well, yes, you may need to wake them for feedings as directed by your pediatrician. For healthy, thriving babies over 1 month, you can let them sleep during naps, but consider waking them if a nap goes too long and pushes bedtime too late. Never wake a sleeping baby at night unless medically necessary.

How dark should my baby's room be for sleep?

Ideally, your baby's room should be dark enough that you can barely see your hand in front of your face. Darkness helps trigger melatonin production, the sleep hormone. Use blackout curtains or shades to block outside light, especially for naps. A small, dim nightlight is fine for nighttime diaper changes, but keep it away from baby's direct line of sight.

Can I start a bedtime routine with a newborn?

Absolutely! It's never too early to establish a simple, calming bedtime routine. Even newborns benefit from the predictability of a consistent sequence of events before sleep. Keep it short and sweet at first, maybe just a diaper change, pajamas, feeding, and a lullaby. As your baby grows, you can add a bath, books, and other calming activities.

Why does my baby fight sleep when they're obviously tired?

Overtired babies often fight sleep because their bodies release cortisol, a stress hormone that makes them wired and harder to settle. This is why watching wake windows is so important. Try to catch your baby's early sleep cues like yawning or eye rubbing, and start the sleep routine before they become overtired and fussy.

Do I need to follow the same nap schedule on weekends?

Consistency really helps reinforce your baby's internal clock, so try to keep nap times within 30 minutes of your usual schedule, even on weekends. That said, life happens, and occasional variations won't derail everything. If you have weekend outings planned, do your best with one nap on the go, but try to protect at least one nap in the regular sleep environment.

When can I expect my baby to sleep through the night?

Every baby is different, but many babies are capable of sleeping 6 to 8 hour stretches by 4 to 6 months, and 10 to 12 hours by 9 to 12 months. Sleeping through the night depends on your baby's weight, feeding needs, developmental stage, and sleep environment. Some babies achieve this milestone earlier, others later, and both are perfectly normal. Focus on creating healthy sleep habits rather than rushing this milestone.
