Swaddlebees Simplex All-In-One

The second diaper we tried was the Swaddlebees One Size Simplex all-in-one diaper.  All-in-one diapers are made up of one part - the waterproof layer is sewn to the absorbent layer.  When one part is dirty, the whole thing is dirty.  For this reason, this diaper is very daycare friendly.  The only difference between using an all-in-one and a disposable is where the diaper goes when it's dirty (bag to take home vs. trash).  The other important feature of all-in-one diapers is the price - they are generally the most expensive of all the options (other than the hybrid diapers).

This all-in-one diaper has a "tongue" that you can either shove into the pocket between the absorbent layer and the waterproof layer or lay across the top (see second photo below).  The Simplex is unique (at least among the diapers we tried) because if you shove the tongue into the pocket, soft organic cotton is next to baby's bum.  If you lay the tongue across the top, stay-dry fleece is  next to baby's bum.

The tongue has organic cotton on one side...

...and "stay-dry" fleece on the other.

The outside - adjustable with the rows of snaps to the left.

At first, I liked this diaper the best of all the all-in-ones that we tried.  I especially liked the option to have nice cotton during the day and fleece during the night.  After a few washes, however, it became clear that the nice, organic cotton held onto poop stains like whoa (you can probably see some in the photos above).  I also read some online reviews indicating that, if you laid the tongue across the top of the diaper, it slid out the leg hole once the baby began crawling.  Hmm.

Here's the diaper on:

Sumo wrestler! 

This diaper wasn't as bulky as this photo makes it look but the waistband was problematic - it scrunches up beneath the muffin top (see photo).  Making the snaps looser meant that it fell down and making it tighter made it wrinkle up more. When it was wrinkled up, the white part (i.e., the part that will be soaked in pee) peeks out and sometimes wicks moisture onto the clothing.

Although we liked the cotton/fleece option, the fit around the waist, the potential for problems once the peanut can crawl, and the stain factor made this diaper a no-go.
