My baby's yaya insists that Perla is best for removing poop and food stains from baby's clothes but I want her to use natural laundry detergent specifically for babies. Is there a brand that's just as effective as Perla?

Actually quite a number of my friends are using Perla white for washing of their baby's clothes. But, if you want to try a brand that is specifically for babies, one popular brand among mothers is Cycles. http://www.cyclesbaby.com/ It is more expensive as compared to Perla, but it is hypo-allergenic as it does not contain any irritants such as dyes, optical brighteners, enzymes, bleach and fabric softeners. Pigeon is another good and effective brand that you can consider. http://ph.pigeon.com/product/baby-laundry-detergent
