Huggies Kimbies only last 2hours

I purchased buggies dry comfort for my kiddo . day 1 of using it he wet himself after a nap of 2 hours . I thort maybe I'm just putting it on wrong and i continue to ensure that i put it on correctly so by no fault of my own the kimby only allows 2hours before my son who is not being over fed wet himself . This is my 1st time experience i had with buggies seems there quality has gone down as this was not the case i had with my previous child at all . Very unhappy as this leaves me with a pot of bad imbibes
