What size duvet should you get for a new born, baby and toddler?

A New Born / Baby

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

A Toddler

Depending on the size of their bed, choose a cot bed duvet or a single duvet.
