How to get my toddler to eat?

my sons docter changed my sons milk from cows milk to soy because he thought he developed an allegery to it because he had a really bad cold for a month , but he wouldnt drink it so he took him off milk alltogether and a few days before he took him off all milk he was throwing up and had dieahera and now I cant get him to eat hardly any thing.

Go back to the pediatrician for advice. Both of my kids were sensitive to cows milk and were switched to Similac or some other substitute. In fact my son was hospitalized before it was discovered that he couldn't handle reg. formula.
