Yesterday I was looking through back issues of Breastfeeding
Abstracts looking for something on extended lactation and
osteoporosis (info anyone?) and saw this reference.  I was
planning to get and read the article before posting but
since your mom needs to know soon I will pass it on without
delay.

Serum nortriptyline levels in nursing mothers and their infants
by K.L. Wisner and J.M. Perel
Am J Psychiatr
1991; 148: 1234-36

Nortriptyline was not detected in the infant sera. In infants nursed for
50 days or more, there was no evidence of accumulation of the drug
or its metabolites in the infants.  Small amounts of the less active
metabolite 10-hydroxynortriptyline were found in the
two youngest infants (3 & 8 weeks)

BTW nortriptyline can also cause galactorhea
I know because I take a very low dose (10mg) daily
as treatment of fibromyalgia and have had some
breast secretion - and it has been 16 years since
my youngest weaned.
