What does it look like if your baby has a allergic reaction to diaper rash cream?

usually tiny blisters, or a rash, or worse shortness of breath, be careful

It can look like nettle rash or it could just be hot lumps and bumps, I'd get your baby checked over as soon as you can, there could be other causes for the rash, dont panic I'm sure its something simple!

Usually they would develop a rash and/or hives (larger red bumps that would just begin to develop w/in about 30 minutes to an hour at the most). If it is a severe reaction swelling lips and possibly throat/airway. Itching also possible. Unlikely that he/she would be allergic to this but possible. Benadryl is usually first choice if it isn't an emergency but depending on age you may need to contact pediatrician.

Irritated. Red and bumpy. Just red. Tiny blisters... Could be any of those. It could also be a yeast infection. Babies can get them too.
