Go to my journal and do a search for soy! the only good soy is fermented soy
There is lactose free formula, which is considered safer than soy for both boys and girls. It is thought that the phytoestrogens in soy can cause feminization of boys and early puberty onset in girls. It may be a little more expensive than soy, but sometimes it can be covered by your insurance if your pediatrician writes a prescription for it.
If it were me, I would not use soy formula.I've read a lot about soy too and heard that it can effect the thyroid gland and it can increase estrogen levels. Talk to his Pediatrician about what kind of formula your baby can take. Remar
