Baby's First Christmas Pajamas: Sizing, Photo Tips & Keepsake Ideas (2026)

There’s first Christmas with a baby, and then there’s baby’s first Christmas — the one with the impossibly tiny pajamas, the 7am photos you’ll frame forever, and the outfit you’ll probably keep in a memory box long after it’s outgrown.

Here’s how to get it right: the sizing, the photos, and the keepsake-worthy details.

Why First-Christmas Pajamas Deserve Extra Thought

You’ll take more photos on this one morning than in most entire months. The pajamas will appear in holiday cards, grandma’s framed print, and the memory box. This is the one outfit worth choosing deliberately — soft enough for newborn skin, photogenic enough for the mantel, and comfortable enough for a full chaotic day of wear.

Sizing a Fast-Growing Baby for December

Babies grow absurdly fast between fall and Christmas. Our rules:

• Buy their current size. Our bamboo runs a little roomy with beautiful stretch — current size in October/November is still a great fit on Christmas morning.
• Convertible foot cuffs are your insurance policy. Our zip pajamas switch from footie to footless, so one size covers both the tiny-newborn phase and the standing-in-the-crib phase.
• Two-way zippers + fold-over mittens on the newborn sizes mean those 2am Christmas-Eve wakeups stay as painless as possible.

Our 2026 Christmas Drop: One Print, Whole Family

Launching October 15 at 10am MT — one hand-drawn woodland Christmas print, illustrated by Canadian artist Jenica Goertz: deer in little red scarves, foxes, bears and squirrels among snowy pine trees, on deep slate-blue with white piping.

The full size run, all in the exact same print:

• Zip pajamas: newborn to 12/18 months
• Two-piece sets: 18/24 months to 12/14 years
• Women’s set: S–XXL (button-front top + pants)
• Men’s pants: S–XXL

Baby’s first Christmas, in the same print as mom, dad, and big siblings — that’s the photo.

Photo Tips for Christmas Morning

• Shoot in window light. Morning light + bamboo’s smooth finish = glowing photos, no flash needed.
• Get the details. Tiny mitten cuffs, the print up close, baby asleep on a grandparent’s chest — these beat posed shots every time.
• Don’t wait for “perfect.” Wrapping-paper chaos, syrup on the pajamas, the 9pm crash — that’s the real album.

Make Them a Keepsake

First-Christmas pajamas are memory-box royalty. A few ideas:

• Date the tag. Write the year inside the collar with fabric marker.
• Photo tradition. Same pajamas-style photo every Christmas morning — watch them grow year over year.
• Hand them down. We make our bamboo thicker with a premium feel, and many parents tell us their pairs last to the next baby — so yours can make it to the keepsake box too.

Caring for Them (So They Last)

• Wash cold, inside-out — protects the hand-drawn print.
• Low heat or line dry.
• Skip fabric softener (it coats bamboo fibers over time).
