How expensive it is to have a baby with a severe milk protein allergy. These are 14.1 ounce cans. A can cost 43 dollars after tax. I thought Nutramigen was expensive, until we got switched to this amino based formula. There is $430 worth of formula here, and this is all just what the doctor gave us to help us out. She’s also requesting additional samples from her rep to provide us and help offset our cost. We got through 4 a week. Insurance denied assistance because he isn’t on a feeding tube, and we don’t qualify for state assistance unless I quit my job, which right now is very possible, as we would come out ahead until our son is a year old.
