Baby sleep raises a thousand questions, especially when nights are short and fatigue sets in. Parents then desperately search for solutions. Some deeply ingrained beliefs seem logical… but are actually counterproductive, or even dangerous.
Ouatine & Cumulus presents six "good ideas" that are actually bad and should be avoided to help your baby sleep peacefully and in a way that respects their needs.
1. Put baby to sleep on their stomach so they sleep better 🙅
This is undoubtedly one of the most persistent ideas: putting a baby to sleep on their stomach does indeed promote deeper sleep. In this position, the baby is less alert and the risk of more frequent and longer breathing pauses is significant. This position therefore considerably increases the risk of sudden infant death syndrome. Medical recommendations are clear: a baby should be put to sleep on their back, on a firm mattress, without blankets or pillows, until they are able to roll over on their own.
The urge to put them on their stomach can sometimes stem from a need to reassure or soothe them. But rest assured: baby can feel perfectly safe on their back, provided they are well supported and settled. A gentle presence, a hand placed on them, a soothing voice, a confined space, are often enough to calm them.
2. Lulling them to sleep in your arms and then gently placing them in their bed 🤱
What an emotion to see your baby fall asleep peacefully against you… but what frustration when they wake up as soon as they are placed in their crib! This scenario, well known to new parents, illustrates the limits of falling asleep "in arms".
The problem is not carrying your baby or responding to their need for closeness — quite the opposite. It is rather accustoming them to falling asleep in conditions they will not find alone in case of a nighttime awakening. Sleep is a succession of cycles and it is common for baby to wake up briefly between two cycles. If they do not find the cues that allowed them to fall asleep (arms, rocking, body heat), they may need you to fall back asleep.
The goal is not to forbid cuddles - far from it, enjoy them! - but it is important to help baby gradually build independent sleep, in their own bed, safely. A reassuring ritual, a calm presence, a comforter or a cloth with your scent can accompany them in this transition.

3. Eliminating naps so they sleep better at night 😴
“The less they sleep during the day, the better they will sleep at night”: this idea seems logical… but it goes against everything we know about the needs of toddlers. Sleep is not something to be economized; it is a vital necessity for the proper development of the brain and body.
A baby who skips their nap will be more tired, and therefore more irritable, more emotionally fragile, and often more difficult to put to bed. Their stressed body produces more cortisol, a hormone that prevents falling asleep and degrades sleep quality. The result: baby struggles to fall asleep and wakes up more often during the night.

The right rhythm is one that respects their physiological needs. Until 3 or 4 years old, naps are essential — and far from being an obstacle to good nights.
4. Letting them cry to teach them to fall asleep alone 😭
Letting your baby cry without intervening, to "teach them" to fall asleep alone, is a method that divides opinion… and for good reason. While it can, in the short term, lead to falling asleep, it is often due to exhaustion rather than appeasement.
Research shows that crying alone for a long time increases the level of cortisol in the baby's body, a stress-related hormone. In the long run, this can affect their emotional well-being, their emotional security, and their relationship with sleep. A baby who falls asleep from exhaustion after crying has not learned to fall asleep: they have simply understood that their cries no longer elicit a response.
There are other, gentler methods to guide them towards independence: gradual presence, evening routines, or active listening. These are simple but powerful gestures that show baby they are safe and can gradually find sleep on their own.
5. Installing a musical mobile or a nightlight to help them sleep 🎶
Suspended mobiles and colorful nightlights often appeal to parents, but their effect is anything but soothing. A mobile that spins and plays a melody attracts baby's attention, stimulates their gaze, and arouses their curiosity. In other words: it keeps them awake, instead of helping them fall asleep.
As for the nightlight, if it is too bright, it can disturb the production of melatonin, the hormone that promotes sleep. It is not necessary for babies, as the fear of the dark is a fear that appears much later in children.
The best environment for sleeping? A quiet space, dark at night or dimmed during the day, without disruptive noise, with reassuring cues. A small, soft nightlight can be useful for older children… but it is far from essential for an infant.
6. Giving baby a big meal so they sleep through the night 🍼
If you don't like falling asleep after eating a heavy meal, the same goes for babies. Yet, how many new parents haven't heard a relative tell them: "A well-fed baby is a baby who sleeps for a long time." This is another persistent belief, which is based on a confusion between satiety and digestive comfort. A baby who eats too much or too quickly just before sleeping may have difficulty digesting, feel uncomfortable, and… wake up more often.
The best thing to do is to respect their needs and their natural rhythm. A feeding or bottle before bed, yes, but without forcing or overloading their stomach. A baby sleeps better when they feel good, not when they are so full they are uncomfortable.
Trusting your baby… and your parental instinct 👶
Every baby is unique and every family learns to find its own balance. What matters is not to strictly follow ready-made methods, but to get informed, to understand the real needs of toddlers, and to move forward little by little. Sleep is a learning process that is built with gentleness, patience, and trust.
And you, what beliefs have you had to deconstruct since your baby arrived?
