Yes the Kirkland brand baby diapers are fragrance free so they do not contain any fragrances that may irritate your babies or toddlers skin.
Kirkland Disposable Baby Diapers are also lotion free.
However Kirkland Brand Disposable Baby Diapers do contain Latex and artificial dyes as part of their material makeup.
Kirkland has been upfront though about the latex and other ingredients contained in Kirkland Diapers.
So as long as your child does not have a Latex Allergy the Kirkland Brand Diapers will not do your baby or toddler any harm.
However if your baby or toddler has a Latex allergy then you should use diapers such as Pampers, Luvs or Huggies or even Target Up and Up diapers which are all fragrance free diapers.
Or you could use Cloth Diapers which are also latex free and are cheaper to use as well and you can use them on multiple children.
