I see I've caused an uproar, so let me put on an addendum...
I've been studying aromatherapy for a little over a year, just completing a course in it, however, yes, i do suggest you verify your information before dousing your child in anything. I certainly would not use any synthetic fragrances including scented baby powders.
with babies, always use LOW dilution (less than 1%) and Moderation. Use organic oils. and by carrier oil, I should have been more specific, sweet almond oil, organic.
and as an addition to the article on phthalates. Phthalates are also used as platicizers and readily leach out of the plastic into whatever is stored into the containers. they can also be found in plastic toys, teething rings,car seats and other such items. There is evidence that phthalates have estrogenic activity. the lab i used to work in did research with breast cancer and with diabetes and phthalates were used in gene regulation studies. basically, the phthalates have the potential to interrupt normal signalling in the body. so, in addition to lotions and shampoos, i'd also suggest carefully examining all the plastics that come in contact with your baby as well.
