Newborn Sleeping Problems (and Solutions): What to Expect in the First Few Months

It’s a familiar story for most new parents: the house is quiet, the lights are dim, and you’re ready to sleep—only your newborn isn’t. From difficulty settling down to waking up every hour, sleep issues are incredibly common in the early months of life. While some of these disruptions are perfectly normal and short-lived, others may require a bit of strategy and patience to resolve.

At CT Coastal, we know how overwhelming those first few months can feel—and we’re here to guide you through them with knowledge, reassurance, and support. In this post, we’ll explore typical newborn sleeping patterns, common sleep issues from 0-5 months, and practical tips for addressing them—all backed by expert sources.

Newborn Sleep Patterns: What’s Normal?

In the first few weeks, newborns sleep a lot—up to 16-18 hours per day—but in short stretches of 2-4 hours. Their internal clocks (circadian rhythms) are not yet developed, so sleep may seem erratic, with no real distinction between day and night.

From about 6 to 8 weeks, babies may begin to consolidate some sleep during the night and stay awake for longer periods during the day. But the journey to consistent nighttime sleep is gradual, and challenges along the way are to be expected.

Common Sleep Issues by Age

0-3 Months: Confusing Day and Night

  • Problem: Many newborns confuse night and day, sleeping more during the day and waking frequently at night.
  • Why it happens: This is simply a result of immature circadian rhythms.
  • What to do: Help your baby learn the difference between night and day. During the day, keep lights on, engage in play, and don’t worry about household noise. At night, keep things quiet, dark, and boring. Use a consistent bedtime routine—even if it’s just a short lullaby and a diaper change.
  • Reach out with questions: When in doubt about how your baby’s routine is progressing, talk to your provider. At CT Coastal, we’re happy to offer guidance that fits your parenting style and your baby’s temperament.

0-3 Months: Resisting Back-Sleeping

  • Problem: Some babies fuss or resist when placed on their back to sleep
  • Why it matters: Back-sleeping significantly reduces the risk of SIDS (sudden infant death syndrome), and is strongly recommended by the American Academy of Pediatrics.
  • What to do: Swaddling (safely and appropriately) can help babies feel more secure on their backs. If your baby rolls over while swaddled, it’s time to stop swaddling for safety. Try placing them on their back while drowsy but still awake so they learn to settle in that position. If you’re unsure whether your baby is safe to swaddle or showing signs of rolling early, talk to your provider during your next visit.

3-4 Months: Sleep Regression

  • Problem: Your baby was sleeping a little longer—and suddenly starts waking more often again.
  • Why it happens: Around 3 to 4 months, babies experience a major developmental shift in how they sleep. They begin transitioning between sleep cycles like adults and may wake up more easily.
  • What to do: This “4-month sleep regression” is frustrating but temporary. Stay consistent with your bedtime routine, give your baby a few moments before intervening during night wakings, and avoid overstimulation during nighttime feeds.

4-5 Months: Short Naps, Frequent Waking

  • Problem: Your baby only naps for 30 minutes and wakes multiple times at night.
  • Why it happens: Babies at this stage are becoming more aware of their surroundings and may wake between sleep cycles.
  • What to do: Begin practicing gentle sleep training techniques such as “pause and respond,” where you wait a few minutes before soothing your baby to see if they can settle themselves. Also, ensure your baby is getting enough daytime sleep—overtired babies often sleep worse at night.

When Is It a Concern?

While most sleep issues are normal and will resolve with time, there are instances when it’s best to consult your pediatrician:

  • Your baby isn’t gaining weight and seems unusually sleepy.
  • Sleep issues are accompanied by signs of reflux or breathing difficulties.
  • Night waking becomes extreme or disrupts feeding and growth milestones.

Persistent sleep disturbances can sometimes signal underlying medical issues such as reflux, allergies, or more rarely, infant sleep disorders.

Sleep Tips That May Work at Every Stage

No matter what age your baby is, some strategies work across the board:

  • Stick to a bedtime routine: A predictable sequence of events helps signal to your baby that it’s time for sleep.
  • Watch wake windows: Young babies can only stay awake for short periods before becoming overtired. Pay attention to age-appropriate wake times—typically 45-90 minutes for newborns.
  • Create a sleep-friendly environment: Keep the room dark, cool, and quiet. A white noise machine can help muffle outside noises and soothe your baby.
  • Avoid sleep props (when possible): Rocking or feeding to sleep can create associations that are hard to break. While it’s okay for younger infants, try gradually teaching your baby to fall asleep in their crib as they get older.

Be Patient: Every Baby Is Different

There’s no one-size-fits-all solution to newborn sleep challenges. Every baby has their own rhythm, and sleep habits evolve rapidly in the first few months. The most important thing?

Be patient—with your baby and yourself.

By understanding what’s normal, responding with consistency, and seeking help when needed, you’ll lay the groundwork for healthier sleep patterns as your baby grows.

As exhausting as these early months can be, they’re just a phase—and restful nights are ahead.
