:bunny: I always use a booster, mainly to increase capacity and bulk. At first I used commercially made (Dignity, Tranquility, etc.) but I found the cost factor was out of control, as the per each cost of the booster/liner was often equal to the cost of the diaper.
So I started to use other disposables (pull-ups, small size briefs) trimmed to the pad section with slits cut in the plastic backing (to assure liquid would pass through to the main diaper).
I usually prep up 20 -30 boosters at a time, so its simply a matter of placing the "booster" in the diaper before a change to truly double the capacity without leaks.
This creates the kind of high capacity, bulky diaper I prefer, without the constant cost over-runs caused by Molicare, Abena and Bambino diapers. In fact I use the booster with Molicares, so there you have it. :bunny:
