Ensure hygienic practices especially when feeding, changing of diapers and bathing. You can use savlon liquid disinfectant and SEBAMED soap which is mild in babies skin.
If after all these, the rashes persist then you will have to visit a paediatric dermatologist for further management, because different rashes have different causes. I hope this helps.
