What kind of diapers do you use? 1 out of 2 children suffer from some sort of diaper rash if they are in disposable diapers. I would give cloth diapers a go. It's pretty standard that cloth diapered babies never or seldom get diaper rashes. Here is some great information:
Anatomy of an Unhealthy Diaper
Sodium Polyacrylate Crystals Is the clear, absorbent gel that absorbs moisture in the diaper. This superabsorbent polymer (SAP) was removed from tampons for causing Toxic Shock Syndrome. To date, no studies exist as to whether sodium polyacrylate is dangerous when absorbed through baby's skin for the first 3 years of life, 24 hours a day. Additionally, SAP absorbs all moisture found on skin, including natural moisture needed to keep skin healthy. Baby skin has not developed the outer layer adults have, making baby skin more vulnerable to absorb toxins without the natural oils and mature protective layers of skin to block toxins.
Plastic Barrier Every disposable on the market, even those found in health food stores, use plastic as its barrier. Plastic doesn't breathe. It is hot. It promotes bacteria growth. Our skin is an organ that needs to breathe.
Dioxins Dioxins are the by-product of the bleaching process, and one of the planet's most hazardous poisons. They are a highly toxic carcinogen and endocrine disruptor. The archives of Disease in Childhood reports that trace amounts of dioxin are present on disposables.
No Breathability Causes Rashes, Possibly Sterility Some babies are ‘rashy’ because air doesn’t circulate in disposables. Cloth breathes. That’s why there’s seldom a need for rash creams with cloth diapers. Also, a 2001 UK study published in the Archives of Disease in Childhood suggests that infant boys who wear disposables could experience impaired fertility as adults. The researchers found that the temperature of the scrotum was almost 2° higher in disposables, this temperature increase, may negatively impact future fertility.
Very Expensive It costs an average of $3000 to diaper a child. Cloth costs a fraction of disposables and can be used by more than one child!
Chemical Stew A study published in late 1999 by Anderson Labs found that lab mice exposed to various brands of disposable diapers experienced asthma-like symptoms. Dr. Rosalind Anderson, lead author of the report, says the following chemicals were among those released from the disposables: xylene and ethylbenzene, suspected endocrine, neuro-, and respiratory toxins; styrene, a suspected carcinogen and respiratory toxin; and isopropylene, a suspected neurotoxin.
Fragrance Added Babies already smell wonderful! Why ruin it with chemicals and perfumes? Some babies can have allergic reactions to the chemical mix, both respiratory, and rash.
Delayed Culture of Potty Training at nearly a dollar a diaper if your child is in pull-ups, that is oodles of money that could be spent on something else. Most kids in cloth train by 2 years old.
TBTs Tributyl tin, a chemical compound which is known to disrupt sex hormones, has been found in disposable diapers, namely: Huggies and Pampers.
