Katie - when my son was a preemie we used Polycose added to his formula. Now that he is older we use Duocal which is similar to Polycose. It only has 25 calories per scoop and the scoops are pretty small. What I like about the Canola is that it has a lot of calories per Tbsp so if we can get 2-3 Tbsp in him a day that is an extra 240-360 calories and it is relatively cheap compared to Duocal. So right now we are using a combination of Duocal and Canola. And my son is g-tube fed at night and I doubt if a child who eats entirely by mouth could/would consume that much oil.
