My 8 month old baby has a rash! What could it be from? see details...? HELP!, my 8 month old has developed a rash on the tummy and lower abdomen. It is really red and bumpy where the diaper tabs are, as if it is irritated from his crawling around. But the rash extends to his upper belly, though not as concentrated. And it goes down to his genital area too. Second time to happen in a week, and without new foods introduced. Could it be a diaper allergy? Or soap? He just had a bath prior to this, and I put a newly washed item on him. Baby soap in the shower and Gain in the laundry. Could it be two different things? He also had a poopy diaper as I changed him? I used diaper rash cream on his genital area, and cortizone on his tummy and diaper tab area. I use pampers babydry diapers. What else should I try?

Summarized question: What should I do if the baby has a diaper rash?
