Hello team,
I have used himalaya large size dipper last couple of weeks. Observed it started rash is located on skin underneath the diaper area. The skin is red and irritated. It appear all over baby's bottom and genital area, or only in certain places.
Note: i was regular user pampers brand. Never observed such problem.
Help me to get proper justification from company.
