At what age can a baby safely sleep with a blanket?

From what age can a baby sleep with a blanket?

A baby should not sleep with a blanket before at least 12 months. This recommendation aims to reduce risks related to sudden infant death and suffocation during sleep. Before this age, it is better to use a sleeping bag or a secured sleeping cocon.

Why is a blanket not recommended before one year?

Babies under 12 months do not have the motor skills to free themselves if they are in difficulty. A blanket can easily:

• Cover the baby’s face and hinder breathing,
• Cause overheating,
• Shift and form a dangerous heap in the bed.

That is why early childhood experts and health authorities (such as the WHO or the American Academy of Pediatrics) recommend waiting until the child has gained enough mobility, generally around 12 to 18 months, before introducing a light, well-fitted blanket.

By baby’s age: how to cover well at night?

From 0 to 6 months: maximum safety

For newborns, it is essential to choose a firm, uncluttered sleeping surface with no loose textiles. Prefer:

• A sleeping bag suited to the season and the baby’s size,
• A well designed cocon that keeps the baby on their back without restraint,
• A light, well-ventilated sleep space such as a cododo bed with a firm mattress.

At this age, a cocon such as the Doomoo Multi Sleep 0m+ can help keep a secure position without additional accessories.

From 6 to 12 months: more movement, increased vigilance

Between 6 and 12 months, baby starts to roll independently, sit up or even pull up. This does not mean a blanket is allowed yet! The risk of suffocation remains significant. Continue to use:

• A sleeping bag appropriate for their size,
• A clear bed, without pillow, large comforter or blanket,
• A stable room temperature (around 19-20°C).

You can use a secured cododo cododo bassinet which makes night feeds and interventions easier while keeping control of the sleep environment.

From 12 months: possible introduction of a light blanket

As soon as baby reaches 12 months and shows good ability to move during the night (rolling, uncovering, covering themselves), you can consider introducing a small, thin blanket, taking care to:

• Choose a size suited to the baby’s bed,
• Tuck it under the mattress so it stays in place,
• Prefer breathable materials such as lightweight cotton,
• Ensure baby is put to sleep on their back at bedtime.

Be careful, every child develops at their own pace: some are only really ready for a blanket at 18 months. Keep observing your baby and adapt according to their abilities.

A well-ventilated room with a light blanket is safer than an overloaded bed.

How to support baby at night without exhausting yourself?

Night wakings are part of parenthood, especially in the first year. To get through them more calmly:

• Arrange a nearby sleeping space (such as a cododo) to avoid tiring trips back and forth.
• Prepare everything you need within reach: muslin, nipple, baby bottle, soft blanket, etc.
• Use reassuring objects for baby such as the BIBS pacifier, which can help them resettle by themselves after 6 months.
• Establish a consistent routine: warm bath, lullaby, cuddle then bedtime, in the same sequence each evening.

FAQ: Parents’ frequent questions

Is it dangerous to have a 6-month-old sleep with a blanket?

Yes. Before 12 months, a blanket can impede breathing or cause overheating. A sleeping bag remains the best option.

Can a special baby blanket be used from birth?

No, even "newborn" blankets should be avoided in the first months. Opt instead for a cocon or a certified sleeping bag from birth.

When can baby sleep with a pillow?

Not before 24 months. Adding a pillow is unnecessary for comfort and increases the risk of suffocation for toddlers.

What is the ideal temperature for baby’s room?

Between 18 and 20°C. A cool but not cold room helps baby sleep better and reduces the risk of nighttime overheating.

My baby kicks off their sleeping bag: should I switch to a blanket?

No. This does not necessarily mean they are ready. Try longer sleeping bags or ones with more freedom of movement.

How can I tell if baby is cold at night without a blanket?

Touch the nape of the neck or the back: if they are warm to the touch, the baby is fine. The hands can be cool without this being worrying.

Can I use a small sheet instead of a blanket?

No. A loose sheet in the crib is as risky as a blanket before one year. Always prefer a sleeping bag.

Should I wake the baby to remove a blanket if they are too hot?

Yes, if you notice heavy sweating, a flushed face or restlessness. Remove the blanket and adjust the nightwear.

Is a blanket necessary in summer?

Often not. A simple summer sleeping bag or light outfit is enough. Over-covering can disturb the baby’s sleep.

My baby wants their comforter to sleep. Is this risky?

Before 12 months, any object in the crib must be closely supervised. Choose a flat, small comforter approved from birth.

Conclusion

Up to 12 months of age, it is essential to remain vigilant: the blanket, despite its reassuring appearance, presents too many risks for the baby’s safety. Solutions designed for their well-being, such as sleeping bags, adapted cocoons or secure cradles, allow you to cover the baby while following international recommendations.
