I used my son's correct size for his weight and I also went up a size, and they still leak. Huggies Overnights didn't have leak problems but for some reason Pull-Ups Nightime can't hold the moisture. Its not fun to have to change the sheets and mattress pad. We even tried to change the Pull-Up while he is sleeping to prevent leakage. Need to look at Huggies Overnights or maybe try another brand.

[This review was collected as part of a promotion.] Pull-Ups Boys’ Night-Time Potty Training Pants are amazing! They absorb so much during the nighttime, which is great for a little one that drinks a lot prior to bedtime! It's nice knowing that you do not have to worry about little one waking up with a wet bed. The fit is right on and they are easy to get on and off as well. The design is adorable. The refastenable, easy-open sides sides are a great product feature as well! Highly recommended!

[This review was collected as part of a promotion.] This product works great for overnight and especially when potty training It’s slightly thicker then regular pull Ups and is soft on the inside as well and there’s a way to determine which one is overnight

[This review was collected as part of a promotion.] My son uses these every night, and we’ve never had a leak yet. They are super absorbent and a great way to prevent over night messes. He really loves the awesome buzz light year design on front, and can’t wait to put it on at night.

[This review was collected as part of a promotion.] These 3-4T Pull-Ups Boys' Night-Time Potty Training Pants are fantastic for potty training and work extremely well overnight for my almost 3 year old. My son tends to pee quite a bit at night and we've had occasional issues with leakage in other brands, but not these! These ones work extremely well to hold onto plenty of liquid overnight, keeping your kid and their bed perfectly dry. They feel very comfortable, and are easy to put on and take off. My son loves Mickey Mouse, so he's less likely to fight me on getting these on him at night when he goes to bed. They work great in the daytime as well. All in all, very happy with these!

[This review was collected as part of a promotion.] My daughter is in the first stages of potty training so she still wets the bed! These hold more then her diapers do she used to leak and now she doesn’t! They have cute little designs it moves with her very well and are a perfect fit

My daughter is 4 yrs. old and still uses Night Time pull-ups. We loved this product until recently when Huggies changed the design. What was the company thinking adding a "Sully" design to the girl's package? My daughter gives us a difficult time every time we come to the Sully pullups and so, now, with every pack of diapers I'm wasting a 1/3 of the package. Please take the Sully design out of the girls packages! I also have the same comment as others regarding sizing - my daughter recently began treatment for leukemia and put on about 6 lbs. She is now about 36 lbs and the 3T - 4T size (up to 40 lbs) is not quite big enough since she seems to peed through them much more often than she used to. Its impossible to find 4T - 5T.

[This review was collected as part of a promotion.] Love the toy story design, one of mine and my son's favorites. These are soft and comfortable and have just enough stretch to get them on like pants and for him to wear overnight. They do seem to hold up better then regular diapers and hold more. Would definitely use again.

[This review was collected as part of a promotion.] My daughter absolutely loved these Pull-Ups Night Time Potty Training Pants. The Minnie Mouse design is her favorite character for sure. They held up throughout the night and kept her dry. The material is soft and gentle on her delicate skin. The fit was perfect and was secure in the leg area. She could move freely without leaks. We are having a much better time potty training at night with these. She feels like a big girl now! Great night time pull up. We will be getting more.

My daughter sleeps extremely deeply, so nighttime potty training is just not happening. We tried a variety of training pants before finding the right ones. The regular ones would leak 3 out of 5 days, so we tried the nighttime ones. These are the ONLY ones that will work on a regular basis. Even after cutting down nighttime liquids, we've still got to use the nighttime designs, and go up a size just to contain all the urine. Still an occasional leak or two, but once a month is much better than 20! My only complaint is the ridiculous need to label everything for "girls" or "boys" and have designs that allegedly appeal to one gender over the other. Unfortunately, it's in ALL kids' products.
