My baby is 7 months old. Her buttock are red and seems like wound. what could be the reason and how to avoid it to happen.?

A. Ru Using diaper too much because the rash or the redness could be due to excessive usage of diaper so please do not use diapers start applying Boroline anti septic cream every one or two hours into that area that is going to heal faster but avoid using diapers for the timing
