Very good
Size: 1 Pound (Pack of 1)
There are two companies that have very little ingredients and this is one of them. I only buy dog treats that are made in the USA very little ingredients for a 1 pound bag so far this is the least expensive I need as small as I can get because I have a Golden and he doesn’t care whether he gets a tiny bit or 25 pound turkey. He wants more so the smaller they are the better it is for me. It must also be made in the USA and have very little ingredients right now. This is it.

Great fit and makes potty training easier
Size: 3T-4T, Unit Count: 84
These training pants have been a big help during potty training. They fit comfortably and feel soft against the skin, more like real underwear than a diaper. The stretchy sides make them easy for little ones to pull up and down on their own, which really helps with independence. They do a good job holding small accidents without leaking, and the fun character designs make my little one more excited to wear them. The pack comes with plenty to last through the training phase, which is nice when you’re going through a few each day. Tip: keep a few extras in the car or diaper bag for outings. It makes potty training on the go so much easier.

Great Pull-ups that Don't Leak!
Size: 3T-4T, Unit Count: 20
I was on the hunt for the perfect potty training pants for my little guy, and Pull-Ups Boys' Potty Training Pants in size 3T-4T turned out to be a great find. We’ve tried a few different brands, but these have been the most reliable. The design is fun and colorful, which my son loves, and it makes him excited to wear them. The fit is spot on for his size (32-40 lbs), and he moves around comfortably without any leaks. The absorbency is impressive – it gives me peace of mind knowing accidents won’t mean a complete outfit change. Overall, these Pull-Ups have made the potty training process a lot smoother for both of us. There are a few things to note, though. The price is a bit higher compared to some other brands, but I believe the quality justifies it. Also, while they are great during the day, we still need a bit more protection at night. I find myself using an extra layer for nighttime just to be safe. The packaging could also be improved – a resealable option would be nice to keep the remaining training pants fresh and organized. Despite these minor issues, I’m really happy with the product, and my son is well on his way to being fully potty trained. Pros: - Fun and colorful design that my son loves - Perfect fit for 32-40 lbs, allowing comfortable movement - Excellent absorbency, minimizing leaks - Helps make the potty training process smoother Cons: - Slightly higher price compared to other brands - Not as effective for overnight use, requiring additional protection - Packaging lacks a resealable option for convenience

These training pants are amazing. My son uses them whenever he’s taking a nap or sleeping throughout the night. I’ve ordered these multiple times and we’ve never had an issue with leaking.
