Baby rash

For the last 2 days I’ve been using Alverno natural bug repellent on my 7 month old daughter. Tonight I noticed she has a rash on her arms, legs, and forehead. It doesn’t really seem to bother her but it has me a little concerned. It’s also been very hot out these last couple of days.

Either way, is there any possible way to get rid of the rash and ease any discomfort that may come these next days.

Like I said it doesn’t seem to bad but I don’t want her to be uncomfortable.

Thank you.
