I have wondered about the whole breastfeeding thing too. Thank you for asking the question.

I was not breastfed. type B+


I did breastfeed all 3 of mine.

The oldest (age 13) only did for 5 months. She now shows signs of AS. Tries to do ALL sports, already shows signs of aggravated inflammation in feet and sometimes other areas when she attempts a lot of physical activity.

The other two for 12 months. No signs of AS. Kind of too early to tell, maybe.
