Plastic pants have never done be any good with disposables on. I don’t know all the different brands of diapers that you have tried, however, I would strongly consider using some with the added leak guards. I know the Wal-Mart brand diaper has then along with depends. I know the secure plus is a good diaper for not leaking for me, but you will feel the wetness of the diaper. I also like the abriform super plus is a great diaper, but its very thick diaper and it sounds like you don’t wont to wear a diaper like that. I never tried there thinner diaper and I would guess is its like the super plus, just thinner in size, and if that’s the case I would think it’s a diaper you would like.
