Instead of Pediasure, I would recommend a healthy milkshake with fruits such as banana, avocado, strawberries and others to ensure that he gets vitamins and minerals.
After all, Pediasure is a processed food and is not recommended unless he is severely underweight or malnourished.
You could try nipping the problem in its bud and find out why he does not eat well. Have small portions of healthy food readily available for him to snack on.
