The company said on its website, "Our Dry Max diapers use the same type of ingredients and materials as our other diapers and in fact, many other disposable diapers on the market. The key difference is simply in how we designed and produced the diaper itself."
And the company said that with testing involving more than 20,000 babies and 300,000 diaper changes, the new diapers for kids up to toddler age are "one of the most mom- and baby-tested diapers in our history."
But Cathy Valentine is one mom who said she not only refuses to buy Pampers Dry Max diapers, she has sworn off all Proctor & Gamble products.
She said her 4-month-daughter had worn Pampers Swaddlers since birth and never experienced a problem. But Valentine, 32, who lives near Detroit, said her daughter's bottom turned pink only an hour after wearing the first Dry Max diaper three weeks ago.
"It just got worse," she said.
She said she put the first diaper on at 2 p.m. and by 9 p.m., her daughter had bright pink spots. When she awoke at 5 a.m., "that's when she had the huge blister," Valentine said.
Valentine took her daughter to the pediatrician and after discussing the situation with him, determined that the only thing that had changed in her daughters life was the new diapers.
"It was hard for him to say 100 percent that it was that,"she said. But "he felt strongly that it was in fact a reaction to the diaper or something in the diaper."
After her doctor said her daughter had a "chemical burn," Valentine called Pampers to ask for a refund, which she received, and filed a complaint with the Consumer Products Safety Commission.
In response to the complaints from parents, Pampers created a dedicated hotline for questions about the new Dry Max diapers.
Still, some doctors say that despite the backlash online, all seems quiet offline.
Dr. Ari Brown, a pediatrician in Austin, Texas, said she hadn't seen one patient come in with a complaint about the new diapers.
But she said that as manufacturers update products, sometimes children respond with contact dermatitis, or skin irritation, from new diapers.
"[They're] irritated or bothered by a particular ingredient in the diaper," she said.
She said it was hard to imagine that anything in a diaper could be potent enough to cause a chemical burn, but said that simple diaper rashes can turn ugly very fast.
"They can head south very quickly," she said.
If a child has an irritation and then urinates and makes a bowel movement, the skin can end up raw or even broken, she said.
"In their effort to make these products better [and] design better diapers, sometimes kids will be irritated by it," she said. "The answer is, if it bothers your child switch brands or products. Every product is not for every child."
