A wonderfully combo of prophetic word, scripture and history
Format: Paperback
A wonderful combo of the prophetic, scripture and history. Amanda Grace puts the truth into this book. Many little but important facts, truths and meanings to words names places etc to expand ones knowledge of who God is and how we all can get personal with Him. I also love and appreciate the reminders and again the truths of how history repeats itself and how now in 2025 we as Gods ppl need to step up once again and perhaps the last time before the door closes. Religion is man made, the Word is not and this book, well written and easy to take to heart will help anyone looking for truth and help in discerning satans twisted lies from Gods truth The Word. Blessings to all who read...

With 76 pants in a pack, I find them to be an excellent value for the price
Size: 2T-3T, Unit Count: 76
As a parent navigating the potty training journey, I can confidently say that Pull-Ups Boys' Skin Essentials Potty Training Pants have been a game changer for both my child and me. Here’s why I love them and what makes them an essential part of our potty training routine.
Comfort and Fit:
One of the standout features of these training pants is their soft and gentle fabric. The Skin Essentials line is designed to be hypoallergenic and includes ingredients like aloe to help soothe and protect my little one’s sensitive skin. The fit is great for my toddler, providing just the right amount of stretch and comfort, which is crucial during this transitional phase. My child can move freely, whether he’s playing, jumping, or running around.
Absorbent and Reliable:
The absorbency of these training pants is impressive. They hold up well during the day and help manage any accidents without causing a mess. I appreciate that they have a wetness indicator, which makes it easy to know when it's time for a change, helping to instill good habits as we continue potty training.
Easy to Use:
Pull-Ups are designed for independence, which is perfect for toddlers eager to take control of their potty training. They pull up and down like regular underwear, allowing my child to practice pulling them on and off, which builds confidence. Plus, the easy-open sides are a lifesaver for quick changes when we’re on the go.
Fun Designs:
Kids love fun and engaging designs, and these training pants deliver! The playful graphics featuring beloved characters make my son excited to wear them. This little touch has made a big difference in how he approaches potty training—he’s proud to wear them and feels like a “big boy.”

Very soft, high quality pull ups, but quite expensive
Size: 3T-4T, Unit Count: 112
We really enjoy this brand of pull ups as they are the softest of all the pull ups and they have adjustable straps on each side of the pull up. Most brands just are pull ups with no bells and whistles, but these have Velcro straps on each side that allow you to adjust the size but more importantly for us, it allows us to change his pull up without having to take the pants fully off. This is really convenient when we’re in a hurry or out for the day. The absorbency is some of the best diapers I’ve ever used. I feel I’m a diaper connoisseur and have tried everything from expensive to cheaper generic brands and we continue to buy these because of the quality, the Velcro straps, and also because of the reduction in substances included in the product, which is quite important for us as my sons skin gets irritated easily. The one thing that’s a negative is that they are very expensive. Diapers in general are crazy expensive but these are more expensive than other brands. I usually buy these in bulk on Sam’s website but saw they were on sale and had a deal where you subscribe and get 25% off so I bought two big packs of 112 diapers and ended up spending around $82 for 224 diapers, which is a pretty good deal. I do wish they would sell these for cheaper and unfortunately don’t think I’ll be buying them from Amazon unless they have deals such as I described above. I do overall recommend them though as they are better than any other pull up brand we’ve ever used.

Gentle on skin, strong on progress
Size: 4T-5T, Unit Count: 60
These Pull-Ups are a win for both toddlers and tired parents. The Skin Essentials design feels ultra-soft and breathable—ideal for sensitive skin and long wear. I love that they’re dermatologist-approved and sized just right for 38–50 lbs, which adds comfort and confidence during potty training.
The cute prints add kid-friendly flair, and the sides are stretchy but easy for little hands to pull down themselves—big bonus for growing independence. With 60 pants per box, it’s a solid value for families going through this milestone, even with the slightly higher price tag.
At $39.09 and backed by Amazon’s Choice status and 4.7 stars across 600+ reviews, they’ve earned their spot in our routine. Bonus: over 1,000 purchases last month show we’re not the only ones loving them.
If you’re potty training and want gentle, effective help for sensitive skin, these Pull-Ups check all the boxes.
