Typical Sleep Behavior in Babies 3 to 6 Months (Grand Rapids, MI Guide)

By around 3 months of age, many Grand Rapids babies begin smiling, cooing, and interacting more with their parents and caregivers. Around this time, sleep usually starts to become a bit more predictable, although every baby is different.

Most babies between 3 and 6 months sleep a total of 10 to 18 hours in a 24‑hour period, including both night sleep and naps.

Normal Sleep Patterns for 3–6 Month Olds

Babies in this age range often:

  • Sleep in stretches of 2 to 3 hours at a time
  • Take about 3 naps during the day (morning, midday, and late afternoon)
  • Still wake during the night for feeding and comfort

In Grand Rapids and across Michigan, it’s common for babies’ sleep to shift a bit with the seasons. During our long, dark winters, babies may nap a bit more or earlier in the evening. In the lighter summer months, bedtime might naturally drift later. These changes are normal.

Remember: every baby is different. Some 3–6 month olds sleep longer stretches at night; others still wake frequently. If your baby’s sleep doesn’t match exactly what’s described here, it usually isn’t a problem as long as they are feeding well, gaining weight, and seem generally content when awake.

If you’re worried about your baby’s sleep, growth, or behavior, talk with a Grand Rapids pediatrician or your family doctor.

  • Spectrum Health / Corewell Health pediatric clinics
  • Trinity Health Grand Rapids pediatric services
  • Metro Health – University of Michigan Health pediatric practices
  • Mercy Health primary care and pediatric clinics

These providers all serve families in the Grand Rapids area and can help you understand whether your baby’s sleep is typical.

How Sleep Changes as Your Baby Grows

From 3 to 6 months, your baby’s brain and body are growing quickly. Their sleep cycles become more organized, and many babies start to have a clearer pattern of:

  • Feed → Play → Sleep

Typical changes you might notice:

  • Naps may become shorter but more regular
  • Nighttime stretches might gradually lengthen, especially after 4–5 months
  • Your baby may start to recognize day vs. night, especially if you keep lights dim and noise low at night

Because Grand Rapids has shorter daylight hours in winter and longer days in summer, using consistent light cues can help:

  • Open curtains in the morning to let in natural light
  • Keep evenings calm, with dimmer lighting and quieter activities

Helping Your 3–6 Month Old Baby Settle to Sleep

Most babies 3 to 6 months old still need help to settle and fall asleep. This is a good age to start building positive sleep associations that will help your baby learn to self-soothe over time.

What Are Positive Sleep Associations?

Positive sleep associations are calming, consistent routines that help your baby understand it’s time to sleep. In Grand Rapids homes, this might include:

  • A warm (not hot) bath, especially in colder Michigan months
  • Quiet cuddle time in a dim room
  • Reading a short book or singing a soft lullaby
  • Using a white noise machine to gently mask outside sounds (like traffic or winter snowplows)

Sleep Associations to Use with Caution

Some settling methods can be hard to continue in the long term, such as:

  • Holding or rocking your baby until they are fully asleep every time
  • Feeding to sleep at every nap and bedtime

These can create strong sleep associations, which may lead your baby to expect the same help every time they wake during the night. Over time, this can be exhausting for parents.

Instead, try to:

  • Comfort and soothe your baby
  • Then put them down in their crib or bassinet when they are sleepy but still awake

This helps your baby learn to fall asleep on their own, a skill that becomes especially helpful as they get older.

Feeding and Sleep: What Grand Rapids Parents Should Know

Babies aged 3 to 6 months still need regular feedings day and night, whether they are:

  • Breastfed
  • Formula fed
  • Or a combination of both

Common Myths About Feeding and Sleep

  • Myth: Giving formula to a breastfed baby will make them sleep longer.
    Fact: Research shows that switching to formula does not reliably help babies sleep through the night.

  • Myth: Starting solid foods early (before about 6 months) will make a baby sleep better.
    Fact: Early solids do not improve sleep and can sometimes cause digestive upset.

Being breastfed or formula fed does not determine when your baby will start sleeping through the night. All babies are different, and many healthy babies still wake at night for feeds well past 6 months.

Avoiding a Strong “Feed-to-Sleep” Habit

Babies can easily learn to associate feeding with falling asleep. Over time, they may feel they need to feed every time they wake, even if they’re not truly hungry.

To reduce this:

  1. Feed your baby when they are hungry.
  2. Play or interact with them after feeds when they are alert.
  3. When you see tired signs (yawning, rubbing eyes, looking away, fussing),
    • Take them to a quiet, dim room
    • Put them in their crib or bassinet drowsy but awake

If your baby is crying a lot, difficult to settle, or their sleep suddenly changes, contact your pediatrician or family doctor in Grand Rapids for advice.

Recognizing Tired Signs in 3–6 Month Olds

Learning to spot your baby’s tired signs can make sleep easier for everyone, especially during long Michigan winters when indoor time increases.

Common tired signs include:

  • Yawning
  • Rubbing eyes or ears
  • Staring into space or “zoning out”
  • Becoming fussy or harder to please
  • Turning their head away from you or toys

When you see these signs, start your nap or bedtime routine. Waiting too long can lead to an overtired baby, which often means more crying and harder settling.

Simple Sleep Routine Ideas for Grand Rapids Families

A consistent routine helps your baby feel secure and can improve sleep quality.

Daytime Nap Routine

  1. Short playtime (tummy time, talking, singing)
  2. Diaper change
  3. Quiet cuddle in a dim room
  4. Place baby in crib drowsy but awake

Nighttime Routine

  1. Feed
  2. Bath (especially helpful in dry, heated winter homes to relax baby; use a gentle moisturizer afterward)
  3. Pajamas and sleep sack
  4. Dim lights, soft voice, no screens
  5. Short story or lullaby
  6. Put baby down sleepy but awake

Keeping this routine similar every night helps your baby understand that sleep is coming.
