Which duvet fillings are best for a baby, toddler and a child?

A Baby

Do not use a duvet on a baby under 12 months of age. Depending on your baby and their preferences you can use a specialist sleep bag, a combination of blankets and sheets or swaddle them.

A Toddler

The most important thing to remember is that younger children can't regulate their own body temperature and can easily overheat. So don't go higher than the recommended 4.0 tog. If the weather is cold, you can give them extra blankets or put them in some extra cosy pyjamas. Because of its excellent temperature regulating abilities, wool fill duvets are an excellent choice for small children, helping keep them warm but preventing them from getting too hot.
Synthetic fill duvets are also a good choice for small children, and are a great value alternative.
Wool and synthetic duvets are both machine washable, making them ideal for dealing with night time accidents. They're also hypoallergenic, and so helpful for children with allergies.

A Child

Children under four years old should have a light duvet, it is recommended to use a tog of 4.0 or less. They can't regulate their body temperature, so a warmer duvet could cause them to overheat, making them unwell.
Older children can have heavier tog duvets, but you should consider the warmth of their bedroom when choosing.
A wool fill duvet is a wonderful choice for children, it will keep them warm in winter and cooler in summer. It's also been proven to increase the amount of deep REM sleep by up to 25%. And better-rested children are happier children. Wool is also naturally hypoallergenic and machine washable, making it a very practical choice.
We'd recommend you use a duvet protector to guard against the risk of night time accidents and spilt drinks.
Synthetic fill duvets are a very practical choice for children. Depending on preference, you can choose a springy, lofty hollowfibre duvet, or a fluffy and soft microfibre duvet. Both are hypoallergenic and easily machine washable.
