There are currently TWO styles of the Thirsties Newborn All in One Diaper. The first is the original consisting of a microfibre-based absorbency, and the second is the natural fibre version. For the sake of simplicity, lets talk about BOTH of these styles in ONE relatives simple post.

I don’t own much in the way of Thirsties. The OS NAIO (Natural All in One) is by far one of my favourite diapers. However, because my favourite local retailer doesn’t carry Thirsties, I don’t tend to accumulate them as quickly as I might. I was pretty excited to order matching bums for my kids, but quickly disappointed when I realized the newborn wasn’t natural fibre… Luckily, this meant I was able to order it AGAIN in the new releases from ABC Kids.

You can buy Thirsties at these retailers:

• LagoonBaby (Canada)
• Cloth Diaper Kids (Canada)
• Nicki’s Diapers (USA)
• My Sweet Pickles (USA)
• Amazon (USA)

Thirsties Newborn Design

Both diapers are very similar. From the outside, they are near identical, but on the inside, we notice a difference in absorbency materials and design. Both of these diapers come with the option of snaps or hook & loop. I have only snaps (and some regret for not getting the hook&loop which is so nice on a wee baby bum. No fighting snaps on tiny little waists). 

The Thirsties Newborn cloth diaper is rated 5-14lbs featuring a single rise setting. It has tiny waist wings that snap onto a single row of waist snaps. The Thirsties Newborn also features an umbilical snap down.

Microfibre Inners

The microfibre-based Thirsties Newborn AIO diaper features a total of four layers of microfiber terry followed by a microfleece stay dry layer. This is characterized by 3 layers of the tongue (conveniently attached at the front of the diaper) and one layer in the body of the diaper.

Natural Fibre Inners

The natural fibre version of the Thirsties Newborn AIO features cotton absorbency. The inner body of the diaper consists of a double cotton layer, followed by 2 soaker pads of 3 layer hemp/cotton (again attached at the front). This offers a total of 8 layers of natural fibre absorbency.

Thirsties Real Life

In real life, the Thirsties Newborn Diaper is adorably sweet and convenient to use. Both models had their perks and both had room for improvement.

Real Life Awesome

• Umbilical Stump Care – Seriously, this is a must-have for newborn diapers in my opinion.
  • I also loved how the stump care didn’t pucker out and leave the insides exposed to clothing. The extra belly panel helps keep this area all-around dry. I sometimes got a pucker of fleece with Easy Peasies and Nuggles Bitte. 
• Trim Natural Fibre – The natural fibre diaper was extraordinarily trim on little Miss. Meanwhile the Microfibre one felt bulky and clunky.
• Sizing: for a newborn diaper the sizing on these feels just right. Not too big or too small. Considering, Little Miss is an average sized newborn, these still had room to shrink for smaller babies, and room to grow depending on the baby. now that she has reached 10lbs, they are feeling a little tight on her, but not as tight as the Born Smart (scale of reference). I’m still readily grabbing them and haven’t thrown them in my ‘too small bag’
  • Personally found the NAIO to fit bigger than the microfibre. We are still snapped down with NAIO but not microfibre at 10lbs.
• Easy to Use – This is a cop out awesome point for any AIO cloth diaper, but in case you’ve forgotten… the Thirsties Newborn AIO is super easy to use and that’s super awesome when its 5am and you can’t even keep your eyes open.
  • also super simple to prep. These diapers were a one wash deal and then they were ready to go. The NAIO did get slightly more absorbent with each wash, but nothing crazy.

Needs Improvement

• Sub Par Absorbency – both styles of this diaper have similarly poor absorbency ratings in my opinion. Little Miss quickly out peed both the microfibre and the natural fibre. I almost always boosted these with a GroVia wipe after the first week.  
• Microfibre Tongue – I found the microfibre tongue on the Thirsties Newborn to be bulky and awkward. While not as large as the Imagine Stay Dry Newborn AIO, the tongue was a little chunky, and overall a bulkier fit compared to the Natural fibre version.
  

  Do you see it? The microfibre is *slightly* bulkier than the NAIO? No? Maybe my imagination? It’s definitely fluffier on the bum.

• I wish I may, I wish I might… 
  • A pocket or some other easy way to add absorbency and have it stay put. It’s slightly awkward to lay a booster under the tongues or on top (then I don’t get the stay dry).
  • Stay Dry NAIO – wouldn’t that be the dream? a Natural fibre absorbent newborn diaper with a stay dry liner for keeping sensitive bums feeling dry.

Conclusions

The Thirsties Newborn diaper is an adorable diaper. I have major regrets about not getting the hook&loop style to compliment my stash. I regret this because I love the simplicity and always perfect size of aplix on my other diapers (i.e. my Sweet Pea AIO, Nuggles Cover, Sweet Pea Cover, even the bumGenius Little)

Do I recommend you add these to your stash? Most definitely.  I think they are a great size and fit on my little baby. Currently, at 10lbs, they are one of my favourite grabs from the cart.

You will want to add some boosters. Newborns pee like crazy; so unless your changing diapers every hour, you will need more absorbency. I was adding a single GroVia wipe and that worked great.
