Please NOTE: The new, taller hookand loop version is the only version available but some pictures still show the older, smaller version of hook and loop. We do need pictures on babies of the new version to replace these pictures. Email yours to Karen@greenmountaindiapers.com to possibly see your baby on this page.

6 pounds 15 ounces, 1 week old in Iris snap size XS, over a newborn Workhorse diaper
XSmall, 2 weeks old, about 6 pounds, over small flat birdseye diaper.
Size small cover over a medium red edge prefold with the front folded down, Snappi fastened, on a 4 month old 17 pound baby. Our chart below says small or novice prefolds for size small covers, but you can get the medium under it by folding down the extra length of the prefold to fit it in there.
9 months old, 21 pounds in size medium hook and loop Thirsties cover over a Cloth-eez prefold (trifolded, placed into the center of the cover). Mom says, "I like this Thirsties Cover better than the snap, it seems to have a higher rise (therefore, more coverage!)"

Medium on 9 month old 16 pound baby. Plenty of room, comfy in all the many positions of baby.
Roomy but works well. Medium on same 16 pound 9 month old. These wrap around the leg lower than Bummis Supers. The style and sizing are different.
What fits with what? Thirsties size changes are at different places than Bummis Supers. Thirsties run a bit larger, taller at waist and lower on the leg. That is, the change from small to medium in Bummis is around 15 pounds, but for Thirsties it's about 18 pounds. So here is a picture showing the prefolds in the covers. You can choose to size-up the prefolds but you'll need to smoosh down or fold down the extra length to fit them in. (See the arrows: XS with small yellow edge prefold, and medium with large brown edge prefold.) Many moms do that and like the bigger diapers in there to get more absorbency and to skip buying a size of diapers. The diapers come down a bit in rise when you fasten the prefold, making them easier to fit the larger diapers in the smaller covers. I prefer matching the prefold to the cover size so that they do not need folding down or smooshing down or tucking in (the combinations without the arrow pointing to them), but do what works for you. Either way works. Thirsties also fit over just about any fitted diaper.
Size large is larger than the size 2 Thirsties Duo cover.
Size Large over an XLarge Workhorse diaper. This is one of the few covers that fits really well over the XL Workhorse. This child is 2 years old and 30 pounds. Old style aplix is shown and the bird print is no longer available, but the fit of the large cover is still the same as shown in this picture in the new colors..
Size Large Thirsties cover is the next size up from the Thirsties Duo size 2 cover.
Wonderful over Workhorse diapers.

Size Large cover shown with a XL toddler green edge prefold. This is one of the few covers that you can really get XL toddler size prefold into easily.
