How do I add healthy fats to my daughter's diet?
Smoothies would be a great breakfast, snack, or dessert! You can put in a lot of healthy things that would add different nutrients. The nice thing about smoothies is that the other ingredients can mask certain tastes, too. 

For adding fats, try adding coconut oil or coconut milk, peanut butter or other nut butter, avocado, or even some other oil that you think is healthy.
