The festive designs behind our kids christmas onesies
Every one-piece in this collection is a soft teddy-fleece, so the fun is in the print rather than fussy extras. Children can pick a cuddly teddy bear, a cheeky reindeer or a sweet candy cane, in colours that run from brown and grey to green and pink. There's a look for the child who wants to blend in with the grown-ups and one for the child who wants to be the loudest elf in the room.
Because they're one-pieces with a full-length zip, they're quick to get on and off, which matters when an excited child wants to be downstairs and unwrapping. They work just as well for lazy festive film afternoons, weekend lounging and the run-up to the big day.
Sizing your kids christmas onesies from toddler to pre-teen
Sizes run 1-2Y, 2-4Y, 4-6Y, 6-8Y, 8-10Y and 10-12Y, covering toddlers through to pre-teens. The fit is regular, so the simplest rule is to choose the size your child usually wears. If they're between two sizes, size up for a little extra room to grow and play. For reference, the children pictured are around 129 to 134 cm and wearing the 6-8Y.
Soft teddy fleece that feels like a giant hug
The fabric is a soft teddy fleece with a gentle stretch, so it moves with a child who is busy and rarely sitting still. It genuinely feels like getting a giant hug, which is exactly what you want for cold mornings and late-night film sessions. Some of the range is made from 100% recycled polyester, a small extra reason to feel good about it.
Matching the whole family
The kids' onesie is the children's slot in a coordinated family look, so the little ones can match their friends and the rest of the household. When you want to bring everyone together for the same festive set, browse the full range of onesies and pick the children's part of it here.
Easy care for children's festive wear
Looking after them is simple. Give them a gentle machine wash at a maximum of 30 degrees, turn them inside out first and wash with similar colours. Avoid tumble drying, ironing, bleaching and dry cleaning, and they'll stay soft and cheerful season after season.
