Hello, I have been using pampers since my baby birth and I never had any issue. But last week the pampers I purchased feels grainy or Sandy whenever I touch it , also grains like keeps coming off on baby skin with usage. I am extremely worried and concerned as to is it safe to use these pampers diapers or should I stop using them? I am also worried of him having any infection and really need an expert advice here. Thank you for your response in advance.
