Hello Lizzy,
Sorry to hear about the past... in reading your story, I would lean to the conclusion you have AS. But I am not a doctor.... but many of your comments really hit home.
I think it may be very good to look at your aunts diet if it indeed works for her... many here follow a No Starch Diet... even if you do not want to follow any of these diets... eating a healthy diet and avoiding much of the junk food in the American SAD diet would help.
Hope you can find some answers so that you can hold your baby... that is too precious to have to give up.
Take care,
Tim
