leaking nappies

As a new mom I tried and tried the brands until I found a nappy that worked for my baby girl. I used the red pack of huggies often until it gave my baby a terrible rash. I then learned of the huggies gold that are uniquely created for girls and boys and decided to try it, although it is the most expensive nappies on the market and I was impressed until recently, its been a couple of months now that I'm using Huggies gold. But all of the sudden its leaking. This is now the 3rd pack Ive bought that's leaking so quickly, i don't know if its perhaps a bad batch. The nappy will be soiled infront and leaking, but completely dry at the back. These nappies are expensive and why should I keep on paying so much for a product that's all of the sudden not worth the money, I might as well switch to a cheaper brand.
