My baby she is 7 months old ,past 1 month she is suffering from allergic like small pimples around the dipper wear, I asked dr. Many times she used to change the creams offen but no use ,is this a food allergy or dipper allergy ? Can anyone help me on this?

try using warm water with cotton to clean everytime you change the diapers. then air for a while before you use the diaper cream (desitin blue colour are quite good for my baby). else try using other types of diapers or cloth diapers. if still not recover, suggest to consult another doctor.
