Food Allergies Treatment

My youngest daughter has a milk allergy so I’ve switched the whole family to soy milk. I’ve heard many people say they use rice milk to cook.

Which is a better choice for a baby with a milk allergy? Enfamil Prosobee or Nutramigen? Which is nutritionally better for them? What are the pros and cons of each formula?
My daughter is 2 months and she is on prosobee because she cannot tolerate milk based formulas. We were on regular enfamil lipil, tried lacto free, and gentlease. All those resulted in projectile vomiting and poor weight gain and eczema. The only one she could stomach is prosobee. I have not tried nutramigen yet.
But i was reading about how bad soy formula supposedly is with the hormones and everything, but i don’t know much about the nutramigen i just know that it is highly processed. What would be the healthiest choice for my baby?
Please no rude comments about breastfeeding. I know that is the best choice for her and I am very depressed about this and i feel like a horrible mom because i didn’t try hard enough with breastfeeding. I wish i could try again. I wouldn’t give up so easy.
Thanks for your answers in advance.

Well here’s the deal, I’ve never liked milk my entire life… I just simply think it’s disgusting. I actually have a couple of questions regarding all of this.
1. Just for the fact that I’ve never liked milk, did I enable my body to make an allergy itself against milk?
2. I understand the difference’s between having a milk allergy and lactose intolerance, but is there a way a person can be both? Whenever I have food that contains any type of dairy, my ears begin to itch like crazy. I went to an allergist and he said I have an allergy to milk… But whenever dairy is involved, quite frankly, my stomach just doesn’t want anything to do with it and cause chaos.
Should I go to a gastroenterologist and get tests done.
3. And is the extreme ear itching the result of my allergy??
I’m just not sure what to do to be honest… It’s a pain that I can’t do much with dairy products…

I plan to supplement with formula next month when my baby will be 3 months old. He has acid reflux and is probably lactose-intolerant / possible milk allergy. Which formula is recommended ? I will be asking the pediatrician as well. But before I speak with him, I wanted to find out what is widely used so that I can ask him if I can use the same for my baby. Thanks in advance for your answers.
