“Why does my 3-month-old not fit into 3-month clothes?”
If you’ve ever muttered this while wrestling a romper onto a squirmy baby, you’re not alone. As new parents, we’ve all had those moments — tags that say one thing, babies who insist on growing at their own pace, and drawers full of adorable outfits that almost fit. That’s exactly why, at Yellow Rabbit, we decided to do things a little differently: we size our baby clothes by weight, not age or measurements. And yes, there’s a whole lot of science (and parent empathy) behind it!

The Truth about Traditional Baby Sizing
Conventional sizing — labeled by age ranges like “0–3 months” or based on body measurements — often misses the mark. Why? Because babies don’t grow like clockwork. A two-month-old can be petite or plump, tall or tiny, and still be thriving.
Retail data backs this up: studies have shown that over 30% of baby clothing is returned due to incorrect sizing, and much of that stems from the gap between labeled age and actual body fit. Then there’s measurement-based sizing — precise, yes, but often overwhelming. Measuring a wriggly baby’s chest, waist, and inseam feels more like a gymnastics routine than a shopping task. And let’s be honest, it doesn’t always guarantee a great fit either.

Why Weight Works Wonders
So, what makes baby weight a better fit guide? Quite literally — everything.
Weight is a far more consistent indicator of a baby’s actual size and comfort needs. Unlike height or head circumference, weight has a direct impact on how clothing fits — think of how a waistband stretches or how snug armholes feel.
At Yellow Rabbit, we design our clothing with stretchy, organic cotton knits that flexes with your baby's movement. When you shop by weight, you're choosing comfort first - no bunching, no riding up, no guessing games.

More Confidence, Less Confusion
Ever heard of decision fatigue? It’s what happens when our brains get tired from making too many choices — and parenting is full of them. From sleep schedules to feeding routines, you already have enough to think about.
That’s why we made a conscious decision to reduce sizing confusion. Clear, weight-based labels help parents make confident choices without second-guessing. You don’t have to translate age into size or compare length charts. You just look at your baby’s current weight, and voilà — the right size is right there.
Psychologically, simplifying the decision process builds trust. When you find a brand that just gets it right, you come back to it — and that’s our goal at Yellow Rabbit. We’re here to be the brand that has your back (and your baby’s belly covered too!).

A Thoughtful Shift — Inspired by You
We didn’t land on this approach by accident. At Yellow Rabbit, every change we make starts with you — the parent. We studied what worked in the industry and paid close attention to feedback from our own community. You told us sizing was tricky. You said comfort mattered more than anything. You asked for less guesswork.
So we listened, we tested, and we made the shift. And the results? Happier babies, fewer returns, and parents who are actually enjoying shopping again.
