Hey, that's why there are grocery stores....., it isn't the end of the world if you don't bake or have time. I like to bake when I have time, but it doesn't make you a bad mom not to.
If you have the interest and patience, it really isn't hard. Some things take a lot of time and practice to get right, like pies for example.
Cookies are great starters, not the hard ones that have to be decorated, but simple one's like "snickerdoodles" or chocolate chip.
We love lemon cookies made from a Lemon Cake Mix, just add 2 eggs, 1/2 cup oil, 1/2 tsp of lemon flavoring, to the dry mix, stir till well blended, roll into balls, bake 8-10 minutes, 350 degrees, done. Tasty, chewy, freeze well and so quick and easy.
Some of the best recipes are the "tried and true" that you find in church or community cook books, or those compiled from women's clubs. Usually they are more simple, great tasting, easier with everyday ingredients, not so "gourmet". Betty Crocker is my friend, too.
Don't forget the box mixes for cakes and brownies, or the cookie dough n the refrigerator dept. at the store, they are good too. You can "bake" the easy way, doesn't have to be a complete from "scratch" recipe. You can still have good bonding time with your kids.
You probably have great expertise in things that some of the "cooking" Mom's don't.
