What I’ve learned about infant sleep as a doula
"Why Won't My Baby Sleep?" Understanding Normal, Unpredictable Infant Sleep
You are sitting in the dark at 3:00 AM, rocking a baby who was sleeping perfectly last night, but is suddenly wide awake and fussy tonight. You are exhausted, your mind is racing with "what am I doing wrong?" and the maternal guilt is starting to creep in.
If this sounds familiar, take a deep breath. You are not doing anything wrong.
Infant sleep is rarely a linear path of improvement. It is a wildly unpredictable, non-linear, and often erratic process. Understanding the why behind this unpredictability is the first step toward finding peace and protecting your own mental health.
Why Infant Sleep Is So Unpredictable
It is helpful to stop viewing newborn sleep as a "problem to be solved" and instead see it as a, often, a biological and developmental stage.
Tiny Stomachs & Feeding Needs: Newborns have very small tummies and need to eat frequently, usually every 2–3 hours, both day and night.
Day-Night Confusion: In the early weeks, newborns have not yet developed their circadian rhythm (internal clock), meaning they don't know the difference between day and night.
Rapid Brain Development & "Regressions": Around 3-4 months, and again around 8-10 months, your baby’s brain is growing rapidly and learning new skills like rolling, sitting, or crawling. This causes "sleep regressions"—periods where a good sleeper suddenly wakes often because their brain is too busy developing to sleep deeply.
Immature Sleep Cycles: Newborns only have two sleep states (active and quiet) and their sleep cycles are short—often about 45-50 minutes. Connecting these cycles is a skill they have to learn.
Sensory Overload: As babies become more aware of the world around them, they become overstimulated, which can make it harder for them to fall and stay asleep.
A Gentle Approach to Supporting Sleep
"Gentle" doesn't mean you won't be tired. It means supporting your baby’s development with empathy rather than forcing a schedule their brain isn't ready for.
Follow Cues, Not the Clock: Especially in the first 3 months, follow your baby’s sleep cues (yawning, rubbing eyes, zoning out) rather than a rigid schedule.
"Drowsy but Awake" (When Ready): Around 3–4 months, you can start putting your baby down to sleep "drowsy but awake" to help them learn to settle themselves. If this causes intense crying, simply wait a few weeks and try again.
Create a Soothing Bedtime Routine: A 20-30 minute routine—bath, book, song—signals that it's time to wind down.
Daytime Light, Nighttime Dark: Expose your baby to sunlight during the day and keep the house dark and quiet at night to help their circadian rhythm develop.
Embrace Contact Naps: If your baby sleeps better on you, and it feels safe for you, that is perfectly okay. Holding your baby can make them feel safe, which reduces cortisol (the stress hormone) and helps them sleep.
Protecting Maternal Mental Health
Your mental health is just as important as your baby's sleep. Chronic sleep deprivation is a risk factor for postpartum anxiety and depression.
Accept Help (Or Ask For It): When someone asks, "How can I help?", give them a specific job. "Can you hold the baby while I nap for one hour?" or "Can you drop off a casserole?".
Shift Sleeping: If possible, create a system where you and your partner (or a support person) split the night. For example, you sleep from 9 PM to 2 AM while they handle feedings, then switch.
The "Good Enough" Housekeeping Method: Let the dishes, laundry, and cleaning wait. Your only jobs right now are caring for your baby and taking care of yourself.
Reach Out: If you feel overwhelmed, anxious, or unable to cope, please talk to your pediatrician or a mental health professional. You are not alone, and help is available.
A Note of Encouragement
It is okay to be tired. It is okay that your baby wakes up at night. It is okay to feel frustrated. You are doing a wonderful job navigating a very intense, temporary phase. This, too, shall pass.
