Fruit Smoothie

My kids are really picky, so sometimes this is one of the only ways I can get fruit into them. My mom taught me this recipe when I was about 10 or 11. I've been making it ever since.

1 cup milk
1 cup yogurt
1 cup frozen fruit
1 medium banana

Blend together till smooth. Makes 2 or 3 servings.

I've tried lots of different fruit combinations, but my favorite is this:
1 cup milk
1 cup strawberry or strawberry/banana yogurt
1/2 cup frozen strawberries & 1/2 cup frozen peaches
1 medium banana
