Cow's milk is not all that digestible for humans. Also, milk today from cow's contains high levels of hormones and antibiotics (which cause all kinds of diseases), to name just two of the horrible things it does to us. Don't get me wrong, I think milk is ok in moderation, but NOT this pasturized toxic garbage that is called milk (which is not fit for human or beast).
Goat's milk is closer to human breast milk and thus easier to digest.
Regarding baby food - I highly recommend making your own from local, organic produce. It's easy, it's healthier, and it does not contain ingredients you would never knowingly feed your children. You could use Jessica Seinfeld's cookbook "Deceptively Delicious" http://www.deceptivelydelicious.com/site/
Formula is not the answer either as it contains fluoride and soy (which is an Excitotoxin and NONE of us should be eating or drinking anything with soy in it (it's not a health food like the industry has conditioned us to believe, they've lied to create a market for a product that's cheap for them to produce and it's a waste product). Do you know, there is not a single animal that will eat a soy bean? It's true, they know it's poisonous. If they eat it they die.
The only time a soy product is safe for consumption is when it's has been thoroughly "fermented" (the longer the better, as in years) and even then, it should be used only as a condiment. Our companies do not have the time required to properly ferment soy, it cuts into their profits. Soy by-products are added to most processed foods today as cheap "fillers". I personally avoid any processed food with a soy.
I can't recall at the moment where the study is that was done in Japan on soy years ago. I will tell you this much, the soy the Japanese ate/eat is fermented properly and they ONLY use it as a condiment! I find it very interesting that companies today will twist studies so they can have a cheap product/ingredient to market - even if it is extremely unhealthy.
Do you know that soy has only ever been used in the Orient and Africa as a food during hard times as a survival food? This product has no business being in any of our foods. It makes me angry that the industry has duped so many people.
Soy also has other issues. Infant formula's and baby foods also contain MSG, another Excitotoxin. An Excitotoxin gets into the brain and causes the neurotransmitters to pulse at an extremely fast rate... which makes the neurotransmitter die (once they're dead, they're gone). Other Excitotoxins include all sugar substitutes.
Here are some links to articles that may help you and other mom's make wiser choices. It upsets me greatly that in this country big companies are allowed to produce products that have led to this countries health problems.
