Do you have an Aldi in Queensland? My kids have never wet through the Aldi disposables. Another thing I used to find, when they were due to go a size up, they would wet through a Huggies nappy. I also found that when putting a Huggies nappy on, I had to make sure I pulled the leak side out so as to make sure it was on properly. When I didn't do this, they leaked through.
