Hi all,
Just listened to a fantastic podcast from an Australian Breastfeeding Association councellor who breastfed through ivf treatment. She goes through all the most common drugs and the situations where it may be appropriate to not wean. See http://mumsright.libsyn.com/ivf-and-breastfeeding
My ivf-concieved daughter is now 11 months and breastfeeding fairly frequently (about 5 times per day) so this topic is of particular interest to me and may be helpful for others considering fertility treatment for second and subsequent children.
