Newborn Santa Claus Onesie for a very first Christmas by the tree

Once upon a first Christmas, the smallest member of the family arrived just in time to steal the show from Father Christmas himself. This Santa Claus onesie for babies dresses your little one in soft red flannel with fluffy white trim, a jacket fastened with round black buttons, a black belt with a shiny gold buckle and soft matching trousers. Little black boots with gold buckles and a red hat with a white pompom complete the look, ready for the first photo under the tree and a lifetime of retelling.

First presents and an Infant Santa Claus Onesie under the tree

These baby Santa Claus pyjamas turn the season into a gentle celebration for parents and little ones. The flannel jacket keeps tiny shoulders warm during visits to the grandparents, the boots keep little feet cosy on chilly mornings, and every piece comes off easily when it is time for a nap. Parents and older siblings can wear their own Santa suit, so everyone plays Santa for the Christmas card. Choose this festive outfit today and give the newest elf of the house a first December worth remembering.

Santa’s whole family

Parents can play the real Santa in the matching Santa Claus onesie. Tiny reindeer fans will love the baby reindeer onesie. More festive characters and cosy classics gather in the Christmas onesies collection.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
