I used Arbonne's certified vegan protein shakes while breastfeeding (and still do). I brought the ingredient list to my OB for her okay - I would suggest you do the same. I like them because they don't contain soy which can be a hormone disruptor. They've got 18 grams of protein, 110 calories (only 10 from fat), low carb & sweetened with Stevia. A consultant can give you a print out of the ingredients or you can email me if you don't know anyone. The fiber is really good too, mixed with the protein makes a great meal replacement. My husband & I still have these every morning, yum! Enjoy that baby - they grow fast!
