The Snap-EZ pocket diaper is an option for an even trimmer fit or if you need a larger size range. My daughter, for example, is on the last settings of the one size diaper, but she still has room to grow in a size large sized diaper. On the other side of the spectrum, you may prefer a size small for a newborn and young infant, so it’s pesonal preference whether you prefer to get sized or one size diapers. It has the same elastic section in the front like the one size diaper and the vertical snaps on each side to customize the waist and thigh adjustments. I love this feature in a diaper, because it allows the thighs or wait to be larger/smaller for certain body types for a more personalized fit.
The large fit my DD well and contained messes, but was a little baggy in the back compared to the one size diaper which was much narrower in the crotch and back area. I only mention this to point out that every baby has a different body shape and this extra width in the back would be essential for some larger babies and toddlers for this size. You will want to measure your child and reference their size chart to determine what size and fit will suit your needs best. My daughter may have fit in the last settings of the size medium like she did the one size, but I didn’t want to risk having it be too small so I sized up. All in all they use top quality materials and they contain messes well. Customize the number of inserts according to your child’s wetting patterns for naptime.
