Mine is bb girl, i applied the bum bum area, butt hole, thigh, deep folds at the groin, basically whichever the diaper covers it then avoid vagina
Last time i didnt apply the butthole area coz thought it would be very sensitive, but noticed after poop that part will have redness so now i learnt🤣
Reapply after diaper change
I use mustela, but if the redness come then i apply desitin blue colour
I change my bb diaper 4-6 hourly once, bb is now 2mo
