Sleeper Size Chart
The best night's sleep starts with the perfect fit. That's why we developed our Sleeper Size Chart: to walk you through every portion of size and make sure your baby enjoys maximum comfort. From newborn to toddler, we have listed sizes with dimensions so you can shop any time, without doubt.
The Dimensions of a Sleeper are body length, chest width, hip measurement, sleeve length, and cuff size. We have thought of every detail in the design and development stage, so your baby can sleep, stretch, and snuggle comfortably. Our sleepers are not just soft—they're built for movement and all-day comfort.
Using our chart, you can find a fit that is nearly custom. Once you get the right size, every Greedy Baby sleeper will be more than clothing; it will be a second skin of comfort and bold style for your baby.
