Mary:
Some great advice from moms, but after having 3 kids and researching products, so many products contain oil and chemicals that penetrate through babies skin, which is much thinner than our own. Everything you put on your baby: wash, lotion, shampoo, diaper cream - all get infused through their skin. The skin is the quickest way to get absorbtion of any type into our blookstream as well. That's why they make all the skin patches from birth control to stop smoking!
In order to protect your baby's skin, you must use products that are pure and botanically based. Not all products, even in the health food store, are pure! Not all doctors or dermatologists know everything either, but luckily there is a company who does research well beyond the most noted ones and does actual skin patch testing to make sure that all their products, regardless of the age of the intended, will not harm, but actually protect and work with the needs and functions of the skin. I may be going far beyond what you wanted to know, but truly believe that what I use for my whole family is for our best interest and the future of our health. If you or any other readers are interested in more information, please feel free to email me. I am more than happy to explain and educate. You don't have to be a doctor, but a wise consumer is the best there is. Do investigate before buying. As you can see, trial and error is not always the best thing when you do your homework upfront. Your little one will be much happier....and so will you. Take care--
