Allergies and intolerances while bfing is a complex area. Sometimes what you eat will not affect your bub and sometimes it will - it depends on level of tolerance and the allergen itself. There is a dietician in WA who does skype and email consults who is amazing with this stuff. She is a Lactation Consultant as well as a dietician specialising in food sensitivities and breastfeeding. If you google Joy Anderson you should find her contact details, otherwise PM me if you would like me to send them to you. I highly recommend talking to her - she is absolutley a guru and it will mean you will have very good information and won't have to guess.
