I tried a few different kinds, the first one was a two part "always fit" that had the cloth diaper and then a waterproof cover with snap in liners for an extra booster if needed. These diaper also are suppose to fit from newborn to toddler so you are only buying one set not different sizes. These definitely didn't work for Oliver's shape (he has a very cute but substantial milk belly and very juicy thighs).
Next I tried the Applecheeks, a waterproof cover with a bamboo insert. It comes in 2 sizes so not the most economical choice but I wasn't happy with the fit of the cover and the fact that he peed through this one in about 2 secends.
