What is actually worth making on your own?

Is it actually worth it to make your own butter, applesauce, pasta, graham crackers/goldfish, yogurt, bread, etc cost/time wise? And if so, where are you buying your flour, milk, and eggs from? Because obviously ingredients matter!

I have a baby and a toddler so I don't have unlimited time but I am trying to figure out what is best for my family. I love cooking and want to raise a healthy family, but I also recognize I probably don't need to do everything from scratch. Which of these products are better bought premade (because we are moderately granola here) and which are better homemade?
