L.P.
It is obvious that this baby has a milk allergy or is lactose-intolerant. It is a proven fact that dairy is not good for runny noses or sinus problems. If the baby was doing better on the soy, mom should have kept her on soy. The money she is going to spend on doctor's visits it going to outweight the price of the soy formula. I feel for you, I taught daycare for 2 years and if the baby is not doing well on the milk then mom is going to have to be the one to make things better for you.
