My daughter has been using them since she was born, she's fine. Never even had a rash. Any diaper can cause that, it's a reaction the baby has with the diaper. All babys skin is different .

well I used one so I won't be using them after this one id rather not see her get blisters and stuff @sktraum

Yes! Happened to my son. I use pampers swaddlers but someone gave me huggies and I used them for one day and my son had blisters all over him. It was horrible.
