I have, and do use, Pampers 6 diapers, and the Goodnites Tru-Fit boosters. Technically, neither is a booster, but rather a soaker. The difference is that boosters let the urine flow on through to the diaper, and will eventually get the diaper full enough that it cannot pass much urine, and will then expand. Quite largely, I may add! Soakers such as the pampers 6 and the Tru-fit soakers do not allow urine to pass through to another diaper, but both expand real well. When I want a really good waddle, I use a Pampers 6 inside the outer layer of the premium diaper, then both a Tena Ultimate Overnight and a Tena Overnight pad, covered by an XP Medical booster. WOW! when all are full!!!! The Tenas, like the Pampers are soakers, but can be modified to all allow urine to pass through before they begin to get really full, and full they will get. If you are wondering how to modify them, there are posts here in ADISC that explain how to do it. It isn't difficult. A seamstress pinwheel works rather well, but locate and read the posts for more information.
