My 18 day old has diaper rash...can anyone suggest me good diaper rash cream??

A. you have to maintain hygiene of perianal / diaper area by cleaning it with soap and water and do tap dry. for normal rash you can apply coconut oil and if it is increasing then go for different rashd cream which is available in the market like rashfree / ezinapi / b4napi / zincal. if there is bleeding and erosion you can also add antibacteriald cream like t-bact.
