My babies(twins) have some rush on the faces and on the hip where pamper linner passes not much though, could it be fungal infection that may require changing their sheets oftenly because its just more evident on face. ve applied candiderm cream, its reducing but fear of steroids any effect.
I think its rash you are trying to say you didn't mention the age of the child anyhow if both are large, breastfeeding children may be difficult to maintain moisture so sometimes might be associated with fungal infection like psoriasis versicolaror else in small child it might be a nappy rash that should be sort out there are a lot of products available in market for nappy rash you can buy it or else show it to the nearest physician and confirm it and go with his opinion too
