Adafruit SCD-40 - True CO2, Temperature and Humidity Sensor - STEMMA QT / QwiicThe SCD 40 is a photoacoustic "true" CO2 sensor that accurately measures the concentration of carbon dioxide (CO2) in ambient air. Unlike sensors like the SGP30, which approximate CO2 levels from VOC gas concentration, the SCD 40 directly measures CO2 in parts per million (PPM), making it a reliable tool for environmental sensing, air quality monitoring, scientific experiments, and ventilation studies. While it is larger and more expensive than some

As a parent, I'm always on the lookout for products that make life easier, especially when it comes to diapers. And let me tell you, these diapers have been a total game-changer! Not only are they the best for my active baby, who's always on the move, but the convenience factor is off the charts. These diapers are designed with active babies in mind. They stay put, prevent leaks, and allow my little one to explore and play without any discomfort. The fit is snug but flexible, providing maximum comfort and protection, whether we're crawling, walking, or just having a playful day at home. But what truly sets these diapers apart is the incredible convenience. There have been times when I was in a real pinch, running low on diapers, and the thought of having to drag my baby to the store was daunting. Thankfully, with these diapers, I didn't have to! The fact that I could order them online and have them delivered straight to my door was a lifesaver. No more lugging around those massive boxes from the store; all I had to do was bring the package inside and put it away. It's a simple thing, but it makes a world of difference in a busy parent's life.

They're not all cracked up to be!!

Size: Size 4, Unit Count: 144

Bought these diapers because I heard such great things about them. But quality of the diaper was very poor. When my son had a wet diaper, the diaper really didn't absorb the wetness, so I would have to be careful when I changed because it would leak out once I tore the sides. I'm on a very tight income and regret chosing these because I don't have any extra funds to replace them and also chose to try these out because my son is a wiggle worm when changing him! Also, consider going down a size because these were huge size difference between size 4 little snugglers and these.

Comfortable, reliable, and super convenient for everyday use

Size: Size 3, Unit Count: 136, Size: Size 3, Unit Count: 136

I’ve been using these diapers for a while now and they’ve honestly made things much easier for us. One of my favorite features is the pull-up (pant-style) design. It’s especially helpful when the baby is active and doesn’t want to stay still during changes. Compared to traditional diapers, these feel much more convenient and quicker to put on. In terms of comfort, they are very soft and lightweight, and my baby seems comfortable wearing them for long periods. I also really appreciate that they are unscented — there’s no strong or artificial smell, which is something I’ve noticed with other brands. Absorbency has been great so far. They don’t feel overly wet even after extended use and have held up through the entire night without leaks, which is a huge plus. The inside material stays evenly distributed and doesn’t become lumpy, even after several hours. Pros: Easy pull-up design (great for active babies) Soft, lightweight, and comfortable No strong scent or odor Good absorbency without feeling too wet Reliable overnight protection Holds shape well (no clumping) Cons: Slightly different from traditional diapers, may take a bit of getting used to Overall, these have been a very reliable choice for us. I’ve already reordered them multiple times, and they’ve consistently performed well. I would definitely recommend them to other parents looking for something comfortable, convenient, and dependable.

Leak Proof!

Size: Size 5, Unit Count: 56

These are great for overnights! They do not like and you don’t have to worry about not putting it in correctly as you struggle with a rolling alligator. I’m a fan because they do not leak like others while the kids sleep.
