When tub time does roll around, go easy on the suds, especially if your little one has a rash of any kind. Soap can be a skin irritant, so if you use it, do so sparingly and try to save it for the end of the bath so that Baby isn't sitting in sudsy water the whole time. Try to use mild products, and if your child's skin is a little dryer than usual, moisturize it with a fragrance-free lotion or cream. Since new skin is sensitive, be careful about what you expose it to. In fact, the fragrance in many baby products can irritate some infants, so you may want to look for fragrance-free preparations.
Some experts believe that an infant's skin is much more absorbent than an adult's.
One reason may be that a baby has three times more skin surface per pound. In addition, an infant's immature liver and kidneys may not be able to efficiently flush out chemicals that are absorbed through the skin. Delicate baby skin can also be irritated by the residue left on clothing by laundry detergents. While many babies can tolerate a variety of detergents, if yours is especially sensitive, you may want to wash her clothes with a gentle product. And avoid clothing with rough, raised seams and scratchy tags.
