Milk Versus Soy Formula

Hi moms! Our baby is currently on soy formula. When his sister was 18 months, we found out that she was allergic to the milk protein, and probably had been since she was an infant. When our second child started on formula, we gave him soy because we didn't want to go through all the colic, etc that we did with our first one. He turned out fine and we have no reason to believe he is allergic to milk. It was just a precaution.
Now with our third little one, I've found no issues with milk for him. I had milk products while nursing with no issues and he has had milk based formula. But for the most part, he is on soy formula because of the fear he has a milk allergy.
So my question is, is there any harm in giving him soy formula as opposed to milk formula? Are there any benefits of the milk based formula that he wouldn't be getting from soy formula? Besides where the protein is coming from, is there any real difference? It appears that they have the same vitamins and minerals, so I'm just curious if there is an issue with keeping him on soy. Personally, I'd rather him be on milk based formula. I don't know why. My husband really wants him on soy because he's afraid he'll be allergic. Thanks for your opinions!

What can I do next?

To agree with most of the previous answers, soy may seem great, but too much of it is incredibly unhealthy in both males and females. I wouldn't suggest using it simply as a precaution.

Hey N.,

Have you explored goat's milk? I had a friend who's son was allergic to milk and soy, and her naturopath gave her a recipe for a goat's milk "formula." I think it's worth checking into, anyway, because you'd be using fresh milk as opposed to a powder, and you'd totally sidestep any worries about milk and soy.

Happy Researching,

There are some very expensive elemental formulas (like Vivonex)on the market for EXTREMELY sensitive individuals (kids and adults) who can hardly eat anything. They are expensive, but it should be mentioned that they do exist.
Soy is risky...not enough said about it because few people really want to know. There is the estrogen like effects,but also the fact that hexane ( A harsh solvent)is used to extract soy protein from soybeans and hexane residues end up in all kinds of foods...including infant formula. No one is testing anything for hexane residue.
The book Baby Matters, by Dr Linda Palmer dives in depth into issues with the different types of formula. Hydrolyzed milk protein formulas may be better tolerated as they have been broken down more...though not completely.
Best to you and your family.

As far nutrients in the formula goes, you should be getting equivalent products. There should not be too much of a difference in composition between the two. Companies make sure that they provide the needed values of the nutrients for infant formulas.

Now, that being said, both cow dairy and soy are common allergens. Breast milk is of course the best and goat's milk is the closest to breast milk, but home made goat milk formulas tend to be labor intensive and you need to make sure you have all the supplements on hand all the time because you don't want you formula to be lacking.

If your child is doing well with the soy formula, I would continue to use it.

Soy has a lot of natural estrogens... the hormone that helps girls develop into girls. Boys who are overly exposed to estrogens as they develop have shown signs that it affects their development. If you know of an allergy that you are avoiding, obviously the allergy is worse than the side effects. http://findarticles.com/p/articles/mi_m3741/is_1_52/ai_11...

Obviously no formula is perfect or can completely replace what nature naturally makes.
Life however throws us all sorts of challenges as moms. Do your research, trust your instincts, and trust that it will all work out. good luck

Hi N.,
My 2 year old son had the same allergy and I remember the colicky nightmares so I understand why your husband would not want to try the milk based formula. Now I am not a doctor and have very little knowledge BUT I do have this friend who has his daughter on only soy formula and now she is allergic to soy. Just look at the ingredients of any package and soy is most likely in it- can you imagine the cost and pain of that?! So you may want to check it all out. If you do try the milk based formula and your little one begins to get cranky, refuses the bottle or has yucky BMs then you know to go back to the soy. GOOD LUCK!

I have heard that you need to be careful with giving boys to much soy as there is a lot of estrogen in it.

Hi N.,
I have some definite negative opinions about soy! I used to assume all soy was healthy, considering the way it is marketed. But when I finally linked some GI issues I was having to eating foods high in soy, it piqued my interest and I was surprised to find so much information on the negative effects of soy. Personally, I believe all foods that are close to their "natural" form are much better than highly processed forms, and I think soy is no exception. I have also read from several sources that soy formula and subsequent diets high in soy can/does affect children hormonally as they develop and grow (as ingesting soy increases estrogen levels). Here is a link for a site that can give you this side of the story about soy (there are so many sources out there, but this is one that I'm familiar with): http://www.mercola.com/article/soy/index.htm

I know you will find as many articles and people who claim the opposite - citing the many health benefits of soy. Of course it comes down to what you and your husband believe and are comfortable with. I applaud you for posing the question! So many people only bother to listen to the prolific advertising paid for by the big food companies!

If you are concerned about your son being allergic to milk, you can have him "scratch-tested" by an allergist. It's relatively quick and painless, and might set your minds at ease (or confirm that you need to stay away from milk proteins). You might also want to look into whether there are other formula alternatives out there that might be available at health food stores (or on the internet, if you don't live near a good health food store).
