When it comes to baby sleep, there’s no shortage of opinions — and unfortunately, a lot of outdated baby sleep advice still circulates among well-meaning family, friends, and even professionals. At full feedings®, we believe sleep should be supported gently, not forced. So let’s clear up 5 baby sleep myths that might be working against you (and your baby’s rest!).

Myth #1: The only way to get a baby to sleep is to let them cry.

Truth: Crying it out is not the only path to sleep. In fact, studies show that babies can develop longer stretches of nighttime sleep when their needs are consistently met during the day—particularly around feeding and wake windows.

“Prolonged infant crying may reflect distress related to unmet needs, particularly feeding, overstimulation, or overtiredness.”

—St James-Roberts et al., Journal of Reproductive and Infant Psychology, 2008

Babies can and do learn to sleep through the night without being left to cry. When we ensure their hunger and sleep needs are met, most babies will begin to connect longer stretches of nighttime sleep naturally.

Myth #2: Rocking baby to sleep creates a bad habit.

Truth: Rocking can be a helpful tool to prevent over tiredness, which is one of the biggest sleep disruptors. You’re not “creating a bad habit” — you’re helping your baby regulate.

“Responsive parenting that includes physical comforting, such as rocking or holding, is associated with improved infant emotional regulation and sleep consolidation.”

— Middlemiss et al., Early Human Development, 2012

Once your baby is sleeping longer stretches at night, you can always shift to other sleep associations. But right now? Rock away.

Myth #3: Baby needs to self-soothe to sleep through the night.

Truth: Self-soothing isn’t a prerequisite for long sleep stretches. If your baby has ever slept longer than 45 minutes, they’ve already connected sleep cycles.

What actually disrupts sleep? Hunger, over tiredness, and too much daytime sleep.

“Circadian regulation and homeostatic sleep pressure are the primary drivers of sleep continuity, not learned soothing behaviors.”

—Jenni & Carskadon, Sleep, 2007

Meet their needs in every cycle first. The self-soothing skills will follow.

Myth #4: Solids will help your baby sleep longer.

Truth: Solids are not a sleep solution. In fact, early or excessive solids can cause babies to take in fewer overall calories.

1/4 sweet potato = ~28 calories
6 oz breast milk = ~120 calories

“There is insufficient evidence that introduction of solids improves sleep outcomes, and in some cases may displace milk intake.”

—Perkin et al., JAMA Pediatrics, 2018

Focus on full milk feedings first. Solids are important, but not at the expense of sleep.

Myth #5: Never wake a sleeping baby.

Truth: Sometimes, you should wake a sleeping baby—especially during the day.

Babies can only sleep a certain amount in a 24-hour period. If they nap too long during the day, it can interfere with nighttime sleep.

“Daytime sleep that exceeds total daily sleep need may fragment night sleep. Structured wake windows help maintain consolidated nighttime rest.”

—Weissbluth, Healthy Sleep Habits, Happy Child, 2015

Wake them during the day to feed, follow wake windows, and protect overnight rest for the whole family.

The truth is, infant sleep doesn’t have to be complicated or harsh — it’s actually quite simple to get babies and toddlers to sleep. When we meet their needs fully and consistently, sleep improves naturally — no crying it out required. This is the foundation of The Full Feedings Method® and we would love to show you how to choose sleep for your family! Our affordable online sleep programs offer gentle, step-by-step guidance to help your baby sleep through the night without ever leaving them to cry.
