I switched to vegan only a week or so after my son was born. He is 2 months old now and i'm still exclusively nursing him with no problem. I haven't had any concerns. Tracking the foods that I have been eating i'm getting all the nutrients I need and then some.
my blog if anyone is interested http://eco-kidfriendly.blogspot.com/
My daughter was 15 months when I became vegan (no flirting, straight over). I was omni just before. No issues what~so~ever. She is now 3 years and 3 months and still breastfeeding at least once daily. Mother nature only puts the good stuff in our breastmilk. The stuff that comes out of your body while detoxing usually exits by other means. Breastmilk is almost always superior to the alternative.
This is my first time really exploring this site and my jaw dropped when I read the title to this post. I am breastfeeding my 7mo old son and just became vegan a few weeks ago (fairly cold turkey). I have felt so alone because there are no other vegans in my life, let alone breastfeeding vegans! Just wanted to say thanks....oh and also, I have not had any detox issues that I'm aware of and my son is as healthy as can be!
I second what imblissful said. Our bodies are wonderful at making sure that very, very minimal amounts of toxins get into breast milk.
Also, keep up the good work with breastfeeding :-) I have a 18 month old son who breastfeeds 4 times a day (during weekdays), and 6 times a day (during weekends), and I don't think he will be weaning anytime yet!
