Yes Huggies diapers are safe for babies and toddlers.
However some babies and toddlers might break out in a rash from the chemicals contained in Huggies diapers but that is not really the diapers fault.
Some kids are more sensitive in their skin when it comes to certain chemicals and many babies and toddlers around the world wear Huggies diapers and don't develop any rashes or chemical burns as a result.
Just like the Pampers diapers they did cause some babies some chemical burns but it was because the babies and toddlers were sensitive to the chemicals.
Many babies and toddlers also wear pampers diapers without a problem.
So if your baby or toddler breaks out in a rash from the Huggies or Pampers diapers or any other diaper then you will just need to switch brands of diapers or go with cloth diapers.
