Beth,

I have an article that may help your mom. It is a small study (n=8) from Italy of 6 moms with macro adenoma and 2 with micro adenoma who took bromocriptine throughout their pregnancy. Lactation should not be discouraged, the study says, noting that one mom breastfed her baby despite being on the bromocriptine.

She worked very hard and picked up a low supply and has been happily nursing her little ever since.  Baby is now 13m.  She mentions B12 but I have no idea about that.  I haven't talked to her in a while - not sure if she is getting a period or not.  I did quickly look in Hale's text so not entirely at a loss.  I have no other current details other than what is in this email but thought I'd get this off to the group and see what you all come up with while I put some thought into it here at my end.   I have her permission to post the following part of her email.  All input welcome.  thanks

The doctors I have talked to so far said I have to wean my daughter and go on bromocrptine in order to conceive. But I want to continue breastfeeding her even during pregnancy.

I have read that vitamin b12 helps with pituitary problems and also help with fertility. But there is no way for me to confirm this other than the blog I read. I was wondering if there is a way given my background for me to continue breastfeeding and be able to conceive. Would you be able to ask this question for me in the discussion board or if there is a way I can ask. I am hoping there is another option like the b12 rather than the bromocrptine. That is safer with breastfeeding.
