Need Substitutions for Yogurt and Dry Cottage Cheese in Recipes

[Guest guest]

I am preparing to start this diet dairy free at first. My son and I

both have a lot of trouble with dairy. I have been collecting recipes

and a lot of the bread/muffin/cookie recipes call for butter, Yogurt

and Dry Cottage Cheese. I know I can use coconut oil for the butter,

but what can I substitute for the yogurt and dry cottage cheese?

Thank you!
