One of those prints that stops you mid-scroll. Pigeon Organics’ Kimono Sleepsuit in Pink Birds is covered in a bold, dense tropical botanical print — sweeping plum and dusky mauve leaves layered in an almost kaleidoscopic repeat on the palest blush pink ground, with small illustrated songbirds nestled throughout: each one with a dark plum wing, a teal green body, a white cheek patch and a tiny dark beak, perching on the branches and looking upward. Clusters of small round teal berries dot the stems, echoing the birds in colour and completing a print that feels genuinely grown-up and collectible.
The kimono-style diagonal wrap front means the sleepsuit opens flat for easy on-and-off without pulling over a newborn’s head — silver snap poppers run from the right shoulder diagonally down to the left waist, with additional poppers along both inner legs for fast nappy changes. The fold-over sleeve cuffs double as scratch mitts for newborns and fold flat once no longer needed; fold-over foot cuffs extend the fit as baby grows. Pale blush pink ribbed trim finishes the neckband and ankle hems in a toning match to the ground. Made from GOTS-certified organic cotton jersey. By Pigeon Organics.

Baby Clothing Size Guide
Sizing can vary between brands, so we've put together this guide to help you find the best fit for your little one. Babies grow at different rates, so always consider your baby's current height and weight alongside their age.
Need help? Get in touch and we'll be happy to advise.
How to Measure
- Height: Measure from the top of the head to the heel, with baby lying flat.
- Weight: Use your most recent health visitor or home scales reading.
- Chest: Measure around the fullest part of the chest, keeping the tape horizontal.
- Waist: Measure around the natural waistline, just above the belly button.
- Hips: Measure around the widest part of the hips and bottom.
- Inside leg: Measure from the crotch down to the ankle bone.
- Head circumference: Measure around the widest part of the head, just above the ears.
- Foot length: Stand your child on a sheet of paper, mark the heel and longest toe, then measure between the marks.
Tip: If your baby is between sizes, we generally recommend sizing up for longer wear, especially for sleepsuits and rompers.

Sleepsuits, Rompers & Dresses: Fit Notes
- Sleepsuits: Size up if your baby is long in the body, as height is the key measurement.
- Rompers: Short-leg rompers are more forgiving; go by chest and weight. Long-leg rompers follow the height guide.
- Dresses: Age and height sizing is usually accurate.
