Hi K.,
Soy formula it is genetically modified. If you do go to formula you may be looking at even an even worse scenario. A friend of mine with a 2 month old figured out any soy she ingests makes her baby ill when she breast feeds. Here is some information to help you make an informed decision.
" Soy Formula's Role in the Peanut Allergy
Additionally, recent studies out of the University of London highlight the role that conventional soy (and soy formula) play in the development of the peanut allergy.
As a result of these studies, the British Dietetic Association advises parents to avoid exposing infants under the age of one to soy. In France, parents are advised to avoid soy for children 0-3 years of age given the risk that it may present.
As the first independently funded research organization, we have sought the expertise and advice of leading pediatric specialists with the highest integrity whose only interests are in protecting the health and well-being of our children. http://www.allergykids.com/index.php?id=4&page=Our_Re...

Breast milk is best, but whether you’re feeding breastmilk or formula in a bottle, use this guide to feed your baby safely. Read this report's press release or go to study findings.
Nipple: Start with a clear silicone nipple.
Latex rubber nipples can cause allergic reactions and can contain impurities linked to cancer.
Bottle: Use glass.
Plastic bottles can leach a toxic chemical called bisphenol A (BPA) into formula. Avoid clear, hard plastic bottles marked with a 7 or “PC.”
Plastic bottle liners: Don’t use them.
The soft plastic liners may leach chemicals into formula, especially when heated.
Water: Use filtered tap water.
If your water is fluoridated, use a reverse osmosis filter to remove fluoride, which the American Dental Association recommends avoiding when reconstituting formula. If your water is not fluoridated use a carbon filter. If you choose bottled water make sure it’s fluoride-free.
Formula: Choose powdered.
A toxic chemical called bisphenol A (BPA) can leach from the lining of metal cans and lids. Liquid formulas have higher levels. Powdered formula is a better bet. If you're concerned about BPA, click here to tell infant formula manufacturers to remove it from their product packaging.
