Reusable Waterproof 100% Nylon Taffeta Diaper Pants for Potty Training & Swimming, Leak-Proof & Rip-Proof, NewBorn (Fits up to 13 lbs), 2 Counts

Yes, these run large but I knew that when I purchased them. I purchased a medium for my 25 pound 18-month-old son who will be potty training soon. I bought them to fit over Under the Nile training pants, size 12-24 months, and they are just about perfect. They are a little "balloon-y" looking, but they do smoosh down under clothes. I probably could go down to a small but I'm afraid the leg holes would be too tight then. They are just right on my guy's skinny thighs right now, with a little room to grow. We used these for cloth diapering in the newborn phase and they worked well then, too. We used them over prefolds. A few notes about durability and other uses for these: We put these on over my son's night diaper (Pampers Extra Protection or Huggies Overnights) because we have problems with dampness. My son pees a ton overnight and these help. My son had the stomach flu a couple weeks ago. He had one of these on when he went to bed, and he woke up with a very full diaper and had pooped all over the place. While this cover didn't hold the mess (there is NO WAY any cover could have) I was very worried that it would be beyond stained. I threw it in the wash with the rest of his poopy bedding and clothing and it came out without a stain on it. Anywhere. It was actually amazing, because it had been covered in poop. So these apparently don't stain easily. Our newborn Dappi is also stain free, despite fielding 8 weeks of newborn poop. Very solid and reliable, cheap, workhorse cover. Not as easy as a wrap cover, but one of the trimmest out there for under clothes, and a great alternative to Gerber "rubber pants" for potty training.

I don’t usually write reviews, but these have been a life changer. My son is 28lbs, so I did order the smaller size (whichever was the medium). One day he had an explosive poop, and EVERYTHING stayed in the diaper/underwear cover. Like came out of the underwear but the cover caught it. No mess other than what was in the cover. I put them over his underwear every time now. So far no leaks. I don’t have to worry as much when he sits on furniture. 100% recommend to potty training mommas. Worth every penny to me.

Our baby is tall and slender, so she needs to wear a size 6 diaper heightwise but is only about a size 4 weightwise. Because her legs are slender and not chubby, the size 6 diapers fit perfectly on her torso to prevent leaks and blow outs out the back, but the diaper legs aren't fitted tightly enough to prevent leaks down her legs. So, we decided to give these rubber diaper covers a try. We sized down, based on reviews, and they were a perfect fit. We doubled up her diapers at night and then put the rubber diaper cover over the diapers. It fit just fine, even with the extra diaper. Nine times out of ten the cover has caught the leak and helped keep her bedsheets dry. Every so often, she leaks a bit around the legs. In those fewer rarer situations, though, it has also helped prevent a big mess. The covers are easy to wash by hand or in the machine on a speed cycle in cold water and then hang dry. They typically hang dry quickly as well. So, we have only needed one 2-pack and just wear one and wash one, but if you don't wash every day you may want to invest in a few packs to last through a week. These diaper covers have given us greater peace of mind at bedtime. We do recommend them for anyone with a similar issue to ours. I'm giving them 4 stars instead of 5 only because they don't 100% completely prevent leaks, but they are very good quality and are unlikely to rip or tear. The diapers we use that worked best overnight are Huggies Skin Essentials. They actually worked better than Huggies Overnights (which were much too big around the legs) and all other Huggies types (we literally tried them all). We found that we could use a Huggies Skin Essentials diaper and then double over it with any other type/brand diaper and then put on the rubber diaper cover. I hope this information helps other parents struggling with a similar issue.

First I want to say this...for all the negative reviews of bedtime soaking through..THESE ARE NOT FOR SLEEPING...They are for potty training a child during the day while you are up and moving through the house. They are not for traveling while trying to potty train use a pullup or easy up or a diaper for travel. I have used these on 2 of my other granddaughters now we are raising our 2 year old granddaughter and starting the potty training process. They fit great in the legs but to me they are the same size as the large which is basically a 2T. This morning we started every 15 minutes to sit on the potty so far no accidents at all she loves the training underwear that goes under these. She feels like a big girl like her cousins. She can pull down both easily pulling up and getting over her bottom is a little harder so Granny helps her. These are not to use alone or for sleeping in they are not meant to hold full bladders read the purpose for these before you buy!!!! Who in their right mind would think these would work for a 6 month old child...they are for POTTY TRAINING not for putting over a diaper for a 6 month old. I would recommend these for the purpose they are meant for. Thank you for a great product.
