Debunking Common Sleep Myths

Sleep is essential for your little one’s growth, development, and well-being. But navigating the sea of parenting advice can lead to confusion, especially when it comes to sleep. Let’s separate fact from fiction by addressing four pervasive pediatric sleep myths and uncovering the truth behind them.

Myth 1: Babies Should Sleep Through the Night by 4 Months Old

Many parents believe that by four months, their baby should be capable of sleeping uninterrupted from bedtime until morning due to the common belief that once baby is >12lbs they are able to sleep longer increments.

Fact: Sleep patterns develop gradually, and most babies continue to wake for feedings, comfort, or developmental milestones well beyond four months. Commonly, a child can sleep through the night by 6–9 months consistently, but the individual variation is huge. Expecting an early miracle can lead to unnecessary stress and feelings of failure. Keep in mind, some babies may wake for a night feeding through 6 months old- and that is okay! Fun Fact: On average it is more common for boys to need night feeds longer than girls.

Myth 2: If Your Baby Wakes at Night, It’s Only Out of Hunger

When babies wake, the first instinct is often to offer a feed. While hunger can be a factor, it’s not the only reason for nighttime awakenings.

Fact: Babies wake for many reasons: teething discomfort, diaper changes, needing reassurance, or simply transitioning between sleep cycles- though sometimes it is hunger! Learning to self-soothe is a skill that develops over time, so responding with consistent, loving sleep cues is key. How to identify if the baby is waking out of hunger vs habit? Check out our blog post on this topic to take a deeper dive but to summarize: waking up repeatedly on the hour, every hour is likely hunger. If baby is waking every night at the same time, this is more likely to be out of habit.

Myth 3: Switching to Formula or Solids Will Guarantee “Sleeping Through the Night”

Many caregivers hope that once solids are introduced or formula replaces breastmilk, their baby will have a longer stretch of sleep.

Fact: While more calorie-dense feeds can help some babies feel fuller for longer, sleep depends on neurological maturity and learned sleep associations—not just stomach capacity. Solids often don’t impact nighttime wake-ups as much as personalized sleep strategies and routines do. When starting solids remember that milk whether breastmilk or formula remains the main caloric intake for a baby until the age of one. The reason your child is not sleeping through the night is likely due to the need for a change in schedule or sleep strategies. It is important to note what worked for one baby may not be what works for yours!

Myth 4: If I Tire My Baby Out Before Bed, They’ll Sleep Better

The idea of wearing out your child until they crash at bedtime seems logical, but it can backfire. Throughout the day, into bedtime we always want to avoid a child becoming overtired.

Fact: Overtired babies produce stress hormones like cortisol that make falling and staying asleep more difficult. Instead of long, exhausting days, focus on age-appropriate wake windows and a consistent pre-sleep routine to help your child wind down.If your child becomes over tired earlier than the typical bedtime, it is recommended to put your child to bed early vs keeping them awake until the desired time. A child going to bed when in a safe zone between under and overtired is always more likely to sleep better than a child who goes to bed too early (undertired) or too late (overtired).
