When I was pregnant my hubby started making milkshakes at night. We swicthed over to fuirt smothies as they are so much better for you.
We don't have a recipe, as we genrally just put a bunch of fruit, (frozen and fresh, whatever we have) in the blender along with some ice and some kind of juice. I have found some juices work better then others, (mango, peach, thicker juices.) Fruit we sometimes use is: strawberries, pinapple, peaches, melon (water, canalope, musk) sometimes berries (blue, rasberry). We almost always throw in a bananna, they make it smoth and creamy. You can add yogurt, milk or sobet if you want. We don't as that tend to add calories and fat and I am lactose intolerant so less milk is better for me.
Good luck and just have fun with the blender and furit.
