As you know it become somehow common for a baby to have diaper rash because of so much using of disposable, not clothes. I guess the most important thing about this is to get back to clothes and do take care of the child health, because it's very important. It's better to prevent diaper rash than trying to repair the problem, but let's talk about some certain diaper rash types in order to know the cause and to prepare for the idea - you have to visit the doctor in any time because it can help you more and give you some good, based on your child, advice:

• there are yeast infections - they could be treated with OTC anti fungal, but it's better to see a doctor for the yeast infections - they could go to blisters and have a reddness area, smaller, bigger, but you have to take proper treatment because it can be painful and you don't really want that for your child.
• sensitive skin can get you to know that your child may have an allergy - to the detergents, to the diapers and also some allergy to the food, skin. Go to the paediatrician in order to find more answers about this condition
• eczema is another rash type and you have to really take care about it in order not to get bigger - eczema is basicaly common, but you can use some basicaly diaper rash cures in order to get rid of it and itchiness and also the pain.
• diaper chafing - is basicaly the most common diapper rash - basicaly the genital area is all read, with a lot of blisters - small and big and you have to do something about it - change the diapers more often or try to get rid of them in order to for your child not to have somehow an allergic reaction to them - an wet and diaper could easily ben the cause to this and it's going to give him/her more discomfort because of the reddness area
• skin rubbing is also a cause of reddness area - intertrigo, this is an infection that happens to most of the people, not only the infants and you have to go to a doctor in order to see what's happening on and to get a better treatment
• only use things like zinc oxide for a moderate rash and try to understand that there are many more diaper rash treatments in order to get rid of it
• seborrhea - is another inflammatory condition and because of it could be the reddnes and other stuff about. 
• try to use butt paste every time you change your child diapers because this is going to protect that sensitive skin - basicaly the idea of this is to "get rid" of sensitivity (that's normal) in order to avoid the rash and the blisters.

   Diapers are a "good" reasons to rashes and because of that most of the people tend to talk more about wearing clothes for your children, not diapers any longer. There may be cases when your children do have problems or even they could be allergic to diapers and becuase of that you should really take care of yourself and protect from this thing. 

   It's better to avoid diapers rashes in order to be sure you're not going to have any further problems with them, which is very important. Remember that diapers rashes may not only be caused by wet and dirty diapers - and not chaging them at time, they can also be inflammation or some viruses, or allergies. So, it's better to see a doctor in order to be sure you're not making mistakes about this thing and you do not risk more problems.
