are you using wet wipes to clean the potty ? if yes, let the wetness dry and then apply some rash cream (I'm using Himalaya rash cream for by 22days old baby) and then put on diaper. you can even pat the part with soft cloth inorder to make it dry

After cleaning apply coconut oil. It works

I go with Aquarian Jasmine. coconut oil is the best. it can be used for the whole body including poop area and throughout the year too especially in winter it helps well

Use Eazinapi or B4 nappi cream. gives imm relief

you can use Dermadew diaper rash cream.. prescribed by my pediatrician. Zinc is very essential to the skin for healing and Dermadew has zinc which works faster.

I would suggest not to use any wipes. Just use fresh water& cotton balls to wipe babys bum. Mothercare cotton balls are really soft& absorbent. Sudocream daiper rash cream is really good.
