Quick answer
For a newborn under 10 pounds, the Try Both Kit Newborn gives you a ready-to-use mix of prefolds and fitted diapers with covers, so you can learn what works. For a baby 8 pounds and up who needs a simple, one-piece diaper, the Thirsties Natural One-Size All-in-One is the easier long-term choice.
What each option actually gives you
The Try Both Kit Newborn is a trial set, not a single diaper. It includes 12 diaper changes: 6 Cloth-eez Prefolds and 6 Cloth-eez Workhorse Diapers in newborn size, plus 3 Thirsties Duo Wrap covers, a pack of muslin wipes, pins, and a Snappi. That mix lets you test two diapering methods without committing to a full stash of either.
The Thirsties Natural One-Size All-in-One is one diaper that adjusts to fit most babies from 8 to 35 pounds, though the brand notes it works best at 4 months and up. It has a hook-and-loop closure and 11 layers of natural fibers: 3 layers of organic cotton in the body and 2 soaker pads with 8 layers of hemp/organic cotton. Because it is one piece, there is no separate cover or folding step.
The real trade-off: learning curve vs simplicity
The kit asks you to learn a system. Prefolds need folding and a cover; Workhorses are fitted diapers that also need a cover. That hands-on practice is the point: you find out which style you actually reach for at 3 a.m. The kit also gives you 12 changes, which is enough for a partial day with a newborn but not a full stash on its own.
The Thirsties AIO removes the folding decision. You fasten it and go. The trade-off is that it is a one-size diaper, so it will be bulky on a very small newborn. The brand itself says it is best at 4 months and up, which means it is not a newborn solution for the first weeks.
Cost and commitment
The kit is a sampler, so you are paying to test two methods rather than to build a full newborn stash. If you already know you prefer all-in-ones, that trial value may be wasted. The Thirsties AIO is a single diaper purchase, so you can buy one to try the fit before committing to a full set. Neither option includes a full diaper stash; both are starting points.
Trade-offs to weigh
- Fit stage: The kit is sized for birth to 10 pounds, so it fits a newborn from day one. The Thirsties AIO starts at 8 pounds but is best at 4 months and up, so it will not give a trim fit on a tiny newborn. If your baby is under 8 pounds, the kit is the only one of the two that will fit now.
- Diapering effort: The kit requires folding prefolds or fastening Workhorses and then adding a cover. The Thirsties AIO is a single piece with a hook-and-loop closure, so there is no separate cover step. Choose the AIO if you want the fewest steps per change; choose the kit if you want to learn which system you prefer.
- Stash building: The kit gives 12 changes, which is a trial amount, not a full newborn stash. The Thirsties AIO is one diaper, so you would need several for full-time use. Budget for more diapers either way; the kit tells you what to buy next, while the AIO lets you test one diaper before buying more.
