weird rash on diaper area??!! (INCLUDING PHOTO BUT HIS AREA IS COVERED!!)

Selina • ♡ Wife to My Superman♡ Mother of 4 babies ♡ Lost My Dad 02.04.19 💐 ♡ 3 babies in heaven.

My 2 year old developed a diaper rash a week ago, nothing unusual about it at first until 3 days later when the diaper rash cream wasn't working. We bought one for stubborn rashes and nothing!! eczema cream for babys and NOTHING!!! I'm planning on taking him to the ER when hubby gets home but wondering if anyone else has experienced This?! My daughter is slowly getting it as well!!

☆☆☆☆UPDATE☆☆☆☆ --> Called his doctor and I sent him the same photo, he told me to kick the diapers and put him in undies immediately! bathing him twice a day as well and that I should see a difference!!! My son's pedi said that my son's skin grew an irritants to the diaper and the diaper material! He said for my daughter (turns 2 in January) he says to put undies on her as well but with pads and kick diapers completely since she can't potty train just yet, she's allergic to the diaper material which sucks!! I still need to remember that just because they don't have it when born doesn't mean they can't develop it later. 😔
