I used pampers when Shannon was newborn up to about the age of 2 and they were fantastic, never had a problem with them, good fit, good absorbancy etc.
However, when she got bigger I found that pampers only went up to size 5+ and they started leaking so tried Huggies who do a size 6 and have found these equally brilliant. So i changed when she got older as my her needs changed.
although wish i had tried some own brands, a friend of mine swears by boots own.
hope this helps
