Mom of 6 approved
Size: Size 3, Unit Count: 78
I'm a mom of 6 and these are the best diapers. No problems. Extremely soft and comfy. Easiest diaper to get on a toddler doing the alligator roll. I put my hands through the leg holes and grab their feet to pull them through for easiest pull on. No problems with blow outs. I love the new tear off feature, so no issue with getting them off. I get them on subscription on Amazon to save money and get the big pack.

Size: Size 5, Unit Count: 100
I absolutely love these Pampers Cruisers 360 Size 5 diapers! As a parent of an active toddler, diaper changes used to be such a struggle—but these have made a huge difference.
The pull-on style is a game changer. I can quickly put them on even when my child is moving around, and the 360° stretchy waistband fits snugly without being too tight. It really feels like little “training pants,” which is great as we slowly move toward potty training.
What impressed me the most is how leak-proof and absorbent they are. Even during long days or naps, they keep my child dry and comfortable. The material is also very soft and gentle on the skin, and we haven’t had any irritation or rashes at all. (They’re actually designed to be gentle and hypoallergenic, which gives extra peace of mind.)
I also love the easy tear-away sides and disposal tape—it makes cleanup so quick and mess-free.
Overall, these diapers are perfect for active toddlers. Comfortable, reliable, and super convenient—I highly recommend them!

It's worth it.
Size: Size 7, Unit Count: 44, Size: Size 7, Unit Count: 44
I would like to provide feedback regarding a recent diaper experience. My toddler, who has a tendency to remove his diaper, has previously used Parent's Choice products since birth without issue. However, I have recently encountered a problem with both their standard diapers and Pull-Ups, specifically concerning the coverage in the gluteal region. This has led to the diaper riding up and causing a significant rash due to friction.
I am pleased to report that after two hours of use, the current diaper has exceeded my expectations. My son has not removed it, and the coverage in the gluteal area is excellent. I will provide an update should any leakage occur. I also appreciate the baby powder scent and the overall quality of the product. While the price point is slightly higher than I typically prefer for diapers, my son is approaching three years old and will soon be transitioning to potty training.

Movement freedom and quick changes: The ideal diaper for active babies
Size: Size 5, Unit Count: 56, Size: Size 5, Unit Count: 56
360° Flexible Fit: The standout feature is the 360° stretchy waistband that adapts perfectly to the baby's body, preventing gaps and allowing full, unrestricted movement.
• Easy On and Off: Being a "Pull-On" style, it slides up in a second. For removal, it features the practical "e-z off" tabs on the sides that tear easily for a hygienic and fast change.
• Designed for Active Babies: The packaging highlights an All-Around Fit specifically engineered for dynamic little ones who need protection that keeps up with them.
If your baby has started moving and diaper changes have become a 'wrestling match' with traditional tabs, Pampers Cruisers 360° are the ultimate solution. They offer the peace of mind of Pampers protection with the convenience of pull-up underwear. A great investment for your child's exploration stage.

Great swaddlers alternative when the Velcro became an issue
Size: Size 3, Unit Count: 136
I bought these because my daughter (12 months) started undoing the Velcro on her diapers, even through her clothes. Finding her soaking wet enough times led me to look for a solution. I really like these and will enjoy them until she finds her way out of them. They’re just as absorbent as Swaddlers and the overnights, and she never gets a rash in them. Only downside is the blowout barrier on the legs is much smaller, so she does have some blowouts out the side. The Swaddlers has more material there to prevent blowouts. These are also cheaper than Swaddlers and overall great quality. Soft and absorbent and I don’t have to worry about her even through a 13 hour sleep at night. That thing will weigh 5lbs when I pull it off her but it doesn’t leak! These are going to be our go to diapers as long as she doesn’t learn to pull them off.
