Its a great product and it has always fit my son perfectly. I would suggest changing the size as soon as your baby fits into a new size. For eg if size a is from 2 -8 lbs and size b is from 5 - 10 lbs, move to size b between 5 and 6 lbs since that seems to be more comfortable for the baby.

I use pampers swaddlers all day for my daughter, she's a size 4. I bought a size 4 and a size 5 for overnight. Both leaked insanely after only 2 hours. The entire bed was soaked and my daughter got a rash because of it. So disappointed in the product.

Swaddlers are my go-to daytime diaper. They are soft and fit my daughter's bottom without leaving gaps to leak out of. I prefer Pampers diapers in general over Huggies, which usually have leaks up the back or the legs. Swaddlers don't do great overnight once your baby is sleeping all night, I used Baby Dry at first, now the overnight diapers.

As a mom of four I have tried a lot of different diapers but Pampers have been the ones I come back to every time. So when I was provided with a free pack of Pampers Swaddlers diapers to try I did not hesitate. The upgraded Pampers Swaddlers with Heart Quilts is even softer for my baby and has the best protection that give me peace of mind, especially at night because I know he won't leak through. Pampers gained a customer for life!

Pampers sent me Swaddler diapers to try for free and they are better than any brand I've tried! The upgraded Pampers Swaddlers with Heart Quilts™ is the softest and has the best amount of protection! Our hospital uses pampers and now I see why they truly are the number 1 brand used by hospitals and parents!

[This review was collected as part of a promotion.] We were first introduced to Pampers Swaddlers in the hospital. This is our first child and being first time parents, we knew this product was the perfect match for us. The blue indicator lines on the front and back of the diaper makes it so much easier and convenient when it comes to diaper changes. There is absolutely no need to open your baby's diaper to disturb them, especially while they are sleeping. One glimpse on the front or back and we can tell if she needs a diaper change.

We love Pampers Swaddlers. Since our son was born, it's the only diaper we trust. The hospital used them, and we were given many packs as gifts. We thought nothing of it until we opened a pack by another brand because we had finished the newborn sized Swaddlers, and our son leaked through 3 diapers in a row. Now we won't use anything but Pampers!

I have 3 kids and we have done the best diapers which weren't all that great, they still leaked. Tried the cheap diapers and that was a huge mistake. We are now stuck on Pampered baby dry because we love the way it keeps my daughter dry through out the whole night. And she's a little monster so we never have had a problem with a Pamper falling off of her when she runs around. I had that problem with my sons and we used other products.

We only buy Pampers Swaddlers after going through multiple other brands. Our little boy has less leaks and/or blowouts with Pampers. They keep his skin dry all night... which is about 11 hours for us. Plus, our little one does not end up with the crystals/gel from the absorbent material in the diaper on his skin in the morning... as was the case with other diaper brands. I wish they were a little bit wider to accommodate our little one's rump (it's hereditary) better; but overall, we are super satisfied!

I tried several different brands of diapers hands down the best by far!! The hospital used these diapers and when we came home we already had some other brands. they just didn't fit right. Pampers Swaddlers fit the best and hold everything in. no diaper rashes. Now its all we buy
