How do I team up potatoes and butter in other to fatten my six year old son?

I love cooking with potatoes. Here are a few food options you could make for your kid. Potato pancakes (latkes), Quiche with sliced potatoes, egg muffins with hash browns, gnocchi with simple white sauce are kid-friendly.

A balance of protein and carbs is a better option than butter and potato. And please stop trying to fatten your kids.
