These diapers are amazing, I love them than most name brand diapers, the prints on them are adorable too. I received size 5 to sample and in my personal opinion they fit like a size 6 though, but that did not bother me. I used them on my nephew when I babysit him. They hold urine very well and are great for over night use. I have not had any issues with leaks. I would consider buying this brand in the future. I love the fact they are ph balanced, that makes me feel safe putting them on him. He has not developed any rashes while using this brand of diaper.
