Hugs to you. IVF meds are hell, I remember. Sigh.
I'm curious as to what specifically about BFing around embryo transfer would endanger a pregnancy. I do know from painful experience that IVF is not like a natural conception in any way, and so some of the rules of a natural pregnancy can't apply. However, I feel somewhat suspicious of this advice you have received... it sounds very very much like advice other pregnant women receive from their doctors about BFing during pregnancies achieved through natural means.
Therefore, not to send you on a wild goose chase or anything, really!
but I think it might be helpful to check out www.drjacknewman.com for information here. He is extremely knowledgeable and does answer email, and there may be information on the site itself that can help as well.
I do understand that IVF is high intensity, high hormones, high emotions, lots of pain, a huge rollercoaster, and I wish you and your family all the best, wherever you decide to go with the BFing of your little guy. At this point you have given him three wonderful years and the difficulties you're experiencing with him might also be there if you were nursing - I can't imagine going through IVF with a three-year-old in tow - you are a strong mama! If you do some more research and it helps you feel better about your decision, or supports any feeling you might have to want to continue BFing, either way you have done great to get this far.
Hang in there.
