i am breastfeeding my 14 week old kiddo and am 3 days away from completing my first whole30. i feel great. i have no idea what effects the program would have had on my milk, aside from better quality milk. my production may have gone up, as well. i'm sure that the real-food that has been pumped through my body could only make my milk rich and clean. i have been grain-free for years now, but whole30 challenged me to really stay away from naughty snacking (gluten-free pretzels, ugh!) and over eating approved foods, like fruits, nuts, etc.
i am now more mindful that what is going into my body, becomes my daughter's food, too. so i'm keeping it simple from now on.
