        Comments about Pampers UnderJams Night Wear - Sizes S/M, L/XL:

        Our son has Autism and didn't potty train during the days until after he was 4. We are not even close to night time potty training. We have tried every nighttime pull up, underwear, and diaper there is and UnderJams is the only one that doesn't leak. I got something else, major brand name, at a store that didn't have Underjams since I was in a pinch and he leaked both night we used them.

              We are using Pampers Underjams for our almost-3-year old son. He is currently going through toilet training, but he is a big kid for his age (about 44" tall and 43 lbs.). The Size S/M fit him great and are highly absorbant. My son also likes the fact that they feel like "big boy" underpants and he can easily pull them up and down himself.I highly recommend this product!

                    My kid is 6 and still wet the bed sometimes. Due to its size, the regular pull-ups did not fit anymore. This product makes him feel confident to sleep, without worries or embarrassment. At first he didn't like the designs of the pants, but he got used to it. The material is very absorbent.

                          Excellent absorbent for overnight. My five-year old son wears them to bed for the just in case nights and they are great! Great value for the price for hard-to-find size.

                            We got these for our toddler when he was learning to potty train and they were terrible. Nearly every night they leaked and the fit was not snug. We got the smaller size and it didn't make a difference. We thought the Huggies were better - no problems with them.

                              I had a big 2 year old 40 Lb and he would always leak through all diapers at night except this one! I'm still working on potty training he is now 3 years old and I still use them at night. You only need one for the whole night. The only thing, If you don't put it on right he might leak a little. Love these diapers saved me from washing my son's sheets almost every day.

                                I bought these for my son (age 4, 40 lbs). Over the past two weeks while wearing these, he has woken up with wet PJs about 90% of the time. Based on the many positive reviews, I would guess it might be a bad match between his shape and that of the diaper. They seem to ride somewhat high on the legs/bottom so maybe better suited to very slender kids ... or for those kids who do wake up to pee at least once (mine doesn't). Whatever the case, I'm disappointed.

                                  These are great for my 4 year old son who is still struggling to stay dry at night. They are the only pull-up I can find that doesn't leak. I love this product!

                                      My 5 year old son still struggles with staying dry at night. He didn't want "baby" training pants so we bought the Underjams after seeing the commercial. They are still bulky, and they leak. They are somewhat quieter than training pants so they help with privacy. I think I'll go back to having him wear underwear at night since I'm having to wash sheets anyway and I'll save the money from buying the Underjams.

                                      It works.

                                        I have 3 years old son and he is still wearing pull ups at night, nothing worked.....no night diapers, no night pull ups. He was soaking wet every morning until we found these pull ups.

                                          My 5 and 3 year old wear these to bed. After trying other brands for night time, these are the only ones that ALMOST never ever leak.
