I’ve been there, pacing the nursery
at 3 a.m., wondering why my baby was fussing. It’s exhausting, but I’ve learned
tricks that work. Let’s explore the causes of infant sleep crying, soothing
tips, and when to check with a doctor in simple words that anyone can follow.
Why Does Infant Crying in Sleep Happen?
Baby nighttime crying is common,
especially in the first six months. Babies aren’t fully awake when they cry.
Their brains and bodies are still learning how to rest. I’ve seen my own baby
whimper during naps—it’s often just part of growing up.
Let’s break down the main reasons
babies cry during sleep.
Baby Sleep Cycles
Newborns have short sleep cycles,
about 45-60 minutes. They move between light (active) and deep (quiet) sleep. While
newborns crying during REM sleep, they might make noises or cry softly without
waking.
- Active Sleep: Babies twitch, smile, or whimper. It’s their dream phase.
- Quiet Sleep: Deeper rest, fewer sounds.
Key Fact: The American Academy of Pediatrics (AAP) says newborns spend 50%
of their sleep in active REM, which explains infant sleep distress.
Actionable Tip: Watch your baby
for 5 minutes before picking up. If cries are soft and stop quickly, they’re
likely in active sleep.
Common Causes of Infant Crying in Sleep
Hunger or Wet Diaper
A hungry tummy or soggy diaper can
cause a baby's nighttime crying. Babies need frequent feeds, even at night.
- Check diapers first—it’s a quick fix.
- Feed on demand, especially for newborns.
I’ve noticed that a clean diaper and a
quick feed often stop the fussing fast.
Gas or Teething Pain
An infant restless sleep can come from
gas bubbles or sore gums. Teething starts around 4-6 months.
- Gas: Try gentle tummy rubs or bicycle legs.
- eething: Offer a cool, safe teether.
Parent Tip: I love giving warm
baths before bed. It eases gas and relaxes my baby, cutting down on the crying during sleep.
Overtiredness or Overstimulation
Too much play or bright lights lead
to an overtired baby crying at night. Babies get fussy when exhausted.
- Dim lights an hour before bed.
- Skip screens or loud toys at night.
Colic or Reflux
Colic in infants and crying is
intense, lasting hours, often in the evenings. Reflux (spitting up) can also
cause infant sleep disturbances and crying.
- Hold baby upright 20-30 minutes after feeds.
- Ask a doctor about reflux drops if severe.
Key Fact: Colic affects 20% of
babies and fades by 4 months, per Mayo Clinic.
Is Infant Crying in Sleep Normal?
Most Baby sleep disturbances are
harmless. It’s often just their body adjusting. But how do you know if it’s
normal or something more?
Normal Crying Signs
- Short cries (under 10 minutes).
- Baby settles with a pat or shush.
- No fever, vomiting, or rash.
I’ve seen my baby cry briefly, then
smile in sleep; it’s adorable and normal!
Signs to Watch For
If cries are loud, long, or with
other signs, check with a doctor. It could be infant night waking and crying
from illness.
- Fever over 100.4°F in newborns.
- Pulling ears or arching back.
- Poor feeding or weight gain.
Actionable Tip: Keep a cry
journal. Note the time, length, and what helps. It’s a lifesaver when talking
to doctors.
Soothing Techniques for Crying Infants
Calming an infant crying in sleep
doesn’t mean letting them cry it out. Gentle touches work fast. Here are my
favorite ways to help.
The 5 S’s Method
Dr. Harvey Karp’s 5 S’s mimics the
womb. I’ve tried this; it’s like a magic wand for soothing techniques for
crying infants.
1. Swaddle: Wrap snugly to feel
safe.
2. Side/Stomach: Hold on side (not
for sleep).
3. Shush: Use white noise like
“shhh” or a fan.
4. Swing: Gentle rocking or
bouncing.
5. Suck: Offer a pacifier.
Safety Note: Always place the baby
on their back in an empty crib. No blankets or toys.
More Quick Fixes
- Walk and Hold: Carry for 5 minutes, sit for 8. A 2022 study found this calms most babies.
- Sing Softly: Your voice is comforting.
- Massage: Stroke back or feet gently.
Parent Tip: I’ve tested white
noise machines with ocean sounds. They mimic the womb and cut the baby fussing
in sleep in minutes.
Sleep Training for Crying Infants
Once the basics are covered, sleep
training for crying infants helps reduce infant crying in sleep. Routines teach
babies to self-soothe.
Create a Bedtime Routine
Start at 6-8 weeks. Consistency cuts
baby sleep disturbances.
- Dim lights at 7 p.m.
- Bath, feed, soft lullaby, bed.
- Same steps every night.
Gentle Sleep Training
You don’t need cry-it-out. Try
fading—stay close, then step back.
- Put the baby down drowsy but awake.
- Pat gently if they fuss, then pause.
Key Fact: Routines reduce night
wakes by 50%, says Pampers.
> Actionable Tip: Use a dim
nightlight. It helps you check on the baby without waking them fully.
How to Prevent Crying Episodes at Night
Prevention starts with a calm, consistent routine.
1. Create a Peaceful Bedtime Routine
Warm bath → gentle massage → soft music → feeding →
cuddles → sleep.
Predictable steps help babies relax and sleep longer.
2. Optimize Feeding Schedule
Feed your baby before they get overtired.
Avoid sugary or stimulating foods if you’re breastfeeding.
3. Support Digestive Health
If your baby has frequent gas or tummy issues, talk to
your doctor about infant probiotics. Healthy digestion means better sleep.
4. Keep Sleep Space Safe and Comfortable
- Use breathable cotton pyjamas
- Maintain moderate room temperature
- Keep the crib clutter-free
5. Reassure During Growth Spurts
Growth can make babies fussier. Offer more cuddles,
patience, and understanding during these phases.
When to Call a Doctor for Infant Crying in Sleep
Most infants' crying in sleep is
normal. But some signs need a doctor’s check.
Call me if:
- Cries last over 3 hours daily.
- Baby arches back or pulls ears.
- Fever above 100.4°F (38°C) in newborns.
- Poor feeding or weight loss.
Parent Tip: I’ve called my
pediatrician for peace of mind. They’re happy to help, so don’t wait.
