I have mcda twins. Age 22 months. Only one of the girls started showing this kind of red bumps (photo attached). No itching. This goes away in 10 mins. Consulted multiple doctors. Changed detergent, lotions, soaps multiple times. Nothing seems to work. It's been 5 months now. Baby is active and is happy baby. This doesn't bother her at all.

I really don't know what to do. Any advice? Please point me to the right direction. I had to stop all nuts, egg, milk etc.
