Hi - I have twins conceived via IVF as well. We haven't talked to them about IVF per se, but we used the occasion of them learning more about sex in the 5th grade "family health unit" to say that, for me, getting pregnant didn't happen the normal way, so a doctor helped us. It was kind of sweet, because in sharing this, I couldn't help but convey how very much we wanted them and how very long we waited. I don't see any reason they need to know the mechanics of IVF at this point, but I also don't see any reason they shouldn't. I just felt the "I had some problems that made it so I couldn't get pregnant the regular way, so a doctor helped us" message was appropriate at their age. I'm sure in time, as they learn what IVF is, they'll figure it out (and certainly if they ask "was it called IVF, I'll say yes). No reason not to share in my opinion, and some PPs bring up a good point about it potentially being important for them to know when they are adults. That said, by the time they're adults, there will hopefully be less mystery/isolation around the issue and the science will be perfected, so, if they need it, they won't have to go through as much as we did.
