More info coming soon, but I wanted to put up a few visual comparisons on some newborn diapers and trainers for those wondering about sizing while I'm working on full blog posts!
Left to right: bumgenius 4.0 one size, all the way snapped down, containing newborn insert only; bumgenius x-tra small; Rumparooz lil joey, micro-preemie disposable diaper (to fit 3-4 pound range)
Top row L to R: size 1.5 to 3 years, 20-33 pounds cotton trainers (like gerber); imse vimse super-large size; minkee blueberry size large (out of production, used for size reference)
Bottom row L to R: blueberry size small, charlie banana one size trainers, blueberry size medium
In the picture, it doesn't look like there is too much size difference, but the blueberry size small are definitely the smallest, with the charlie banana fitting right in between the blueberry size small and size medium. All of the trainers except the size large blueberry pink leopard print are fitting right now, and our little trainer is right at 27 pounds and pushing 35 inches tall. The short story is, I am loving all of these except the fluffy pink leopard right now - for the "catch small accidents, not totally waterproof trainers", can't go wrong with blueberry, charlie banana (note only one size that runs small), or imse vimse trainers!
Hope this helps a little for the short term!
