BABY DIAPER RASH is caused
by irritation of the skin of the nappy area.

Baby diaper rash is caused by not changing
diapers often enough. Some of the chemicals in urine touching
skin long enough become irritating and lead to a red diaper
rash with peeling angry looking skin.

The moisture that collects also makes
a nice living area for yeast infections which look like many
red rings with normal skin in the center.
Treatment of baby diaper rash is to keep the
nappy area dry by regular changing, using more absorbent
gel diapers, or allowing your baby to crawl around for periods
au naturale - i.e. naked. Also zinc poweders to the
affected areas are soothing but if yeast infection is there, a cream
with antifungal properties applied twice a day is also needed.
Baby wipes and soaps are also no-no's
when cleaning the nappy area of your baby with a diaper rash. The
chemicals in these two make the sore skin worse. Use plain cool
water for bathing instead.
Believe it or not, breastfeeding your baby
has been found to lower how bad and often your baby gets diaper rash.
And don't rinse cloth diapers with fabric softener as it makes them
less absorbent.
