I am so excitedI'm trying a new design I just made 3of them to test so maybe I can just wear them without rubber pants-Idon't think they will leak at all. Made them with ZORB material and thin elastic leg openings...don't think I will have any more diaper rash problems anymore.I'm going to fill up my sippy cup with apple juice to "test for leaks"-hopefully they will work well,then I will be rubber pants-free!
