Weighted blankets for kids: from what age, what weight and which safety rules?

Weighted blankets for kids are one of the topics parents ask us about most often. Can you give one to your son or daughter, from what age, at what weight and in which size? The short answer fits in one sentence: a weighted blanket can suit a child who is at least 3 years old and weighs at least 15 kg, with a weight of around 10% of their body weight, provided they can remove it on their own and an adult supervises its use. For a baby or infant, the answer is no, without exception. This guide covers each point in detail to help you decide with confidence, and to know when it is better to ask a healthcare professional first.

Weighted blankets for babies: the answer is no

Searches for “weighted blanket for babies” or “weighted sleep sack” come up often, and we would rather answer plainly: a weighted blanket must never be used for a baby or infant. It is not a question of model, size or a lighter weight. A very young child cannot push off a weight placed on them, nor wriggle free if the blanket slides toward their face. The very principle of a weighted blanket, a gentle, enveloping pressure on the body, is therefore not suitable at this age.

At Tyngda, we do not offer any weighted blanket for babies and we advise against any use before the age of 3, even for a short nap, even under supervision. If your child has trouble falling asleep, talk to your pediatrician or doctor: they will be able to suggest solutions suited to their age.

From what age and what weight?

Two minimum conditions must be met at the same time, never one without the other:

• at least 3 years old;
• at least 15 kg body weight.

These thresholds are safety minimums, not an automatic green light. In practice, our lightest weight is 3 kg. Using the 10% rule, it suits a child of around 30 kg. Between 15 and 29 kg, a child is therefore below our lightest blankets: in that case, we do not recommend a weighted blanket without the advice of a healthcare professional.

Beyond age and weight, watch your child too. Can they say clearly that they are too hot or uncomfortable? Do they know how to push a blanket off and get out of bed on their own? If the answer is uncertain, wait or ask for advice.

What weight of weighted blanket for a child?

The rule is the same as for adults: around 10% of body weight. If you are torn between two weights, always choose the lighter one. For a first blanket, or for a child who is sensitive to pressure, the lighter one is also the best starting point. The chart below shows our reference guide, applied to children and teenagers.

Child’s weight	Recommended blanket weight	Note
Under 15 kg or under 3 years old	No weighted blanket	Never, whatever the model
15 to 29 kg	No weighted blanket without the advice of a healthcare professional	10% is still below our lightest weight (3 kg)
30 to 39 kg	3 kg	Kids blanket
40 to 49 kg	4 kg	Kids blanket
50 to 59 kg	5 kg	Kids blanket
60 to 69 kg	6 kg	Kids blanket
70 to 79 kg	7 kg	Kids blanket, for teenagers

Our Kids weighted blanket comes in 3, 4, 5, 6 and 7 kg, so it can keep up with your child as they grow into their teens. An adult weighs the child and checks the blanket weight before buying, then again over the months: children grow fast, and today’s right weight may not be next year’s. If the weight you chose is not right, we will arrange an exchange for a different weight. To learn more, our weighted blanket weight guide sets out the complete chart, including adults.

What size of weighted blanket for a child?

A weighted blanket covers the body, not the bed. It should not hang over the sides: the weight would then pull the blanket toward the floor and it would slide off during the night. So choose the size according to your child’s height rather than the dimensions of the mattress. The Kids blanket comes in three sizes.

90 × 120 cm, for younger children

This size fits a toddler bed and covers the body of a child up to about 120 cm tall. Keep in mind that the 3 kg weight suits a child of around 30 kg: the small size does not mean a very young child can use it. From $149.90.

100 × 150 cm, for school-age children

It suits children up to about 145 cm tall. It is often the longest-lasting size for a growing child. From $169.90.

110 × 170 cm, for older children and teenagers

Designed for older children, teenagers and petite adults, it covers the whole body without overhanging the bed. From $189.90.

The Kids blanket is filled with glass microbeads and protected by a removable cover attached with ties. You can choose between a dark gray velvet cover, cozier in winter, and a lighter cotton cover in navy blue or light gray. The cover is washed at 40 °C and the insert at 30 °C on a delicate cycle, then air dried.

Safety rules to follow

A weighted blanket is a comfort product. To keep it that way, a few simple rules apply every time it is used:

1. The child must be able to remove the blanket on their own, without help and without effort. Try it together before the first night.
2. The face and head always stay uncovered. The blanket goes over the body, never over the head.
3. An adult checks the weight of the blanket against the child’s weight, when buying and then regularly.
4. The child agrees to it. Never force it: if they push it away, take it off and try again later, or not at all.
5. No swaddling or tight tucking. The blanket rests loosely, without being tucked under the mattress.
6. Watch out for heat. If the child is sweating or says they are hot, lighten the bedding around the blanket or remove it.

A gradual introduction

Rather than starting with a whole night, let your child discover the sensation during a calm moment of the day: a story on the sofa, reading time, a few minutes before falling asleep. Then extend the time at their own pace. Experiences vary from child to child: some enjoy the cocooning effect right away, others need time, and some do not like it at all. All three reactions are normal.

Many parents look for a weighted blanket for a child with particular sensory needs, ADHD or autism spectrum disorder. In these situations, the advice of the team that supports the child (doctor, occupational therapist, psychomotor therapist) is invaluable in choosing the weight, the duration and the right moments to use it. Our general safety advice is set out in the article weighted blankets: risks and precautions.

Alternatives to a weighted blanket for kids

A blanket is not the only way to offer a feeling of weight. For a child who does not yet meet the conditions, or who prefers more localized pressure, other accessories can be considered, always with the same rules for children and a professional’s advice.

• The kids weighted vest is worn over clothes during the day, with the weight spread across the shoulders and chest. It comes in S (1.5 kg, 116 to 128 cm), M (2.5 kg, 134 to 146 cm), L (3 kg, 146 to 158 cm) and XL (4 kg, 158 to 170 cm). It is not for sleeping in.
• The weighted lap pad, from 1 to 3 kg, rests on the lap during reading, homework or quiet time. The child puts it on and takes it off themselves, which makes it a very simple approach.

Comfort product, not a medical device. If in doubt, or for a child, ask a healthcare professional for advice.
