This is bunk
My sons best friend is gay. I know he was never bottle fed. He was breast fed by his mother, me, and another childcare provider until he was three years old.
I made soy burgers but he wouldn't eat them. He has many allergies. Once I was cooking shrimp and he threw a toddler tantrum, hitting me and crying.
A year later when he was tested the report said, "Shrim - Could be fatal."
He is now 6'4", a nice man, and my friend. Actually I see him more than I do my own son. Sometimes he tells me what my own kid is doing first.
My DH is like a father to him.
