Hi B. - I also used the pampers swadlers until I had no choice but to go to a size that they no longer made them in, and I went to the "Huggies Supreme" brand. Not the regular brand - the Supreme brand. I have not had any issues with leaky diapers, I actually buy my daughter the "huggies overnight" for nightime and she does really good with those as well.
Good luck!
