Infertility when you have a kid

I do not want to minimize how stressful/upsetting it is for someone else to be unable to have a second (or third, or fourth) kid, but for me there is something very different about infertility now that I have a child.  I really want a second child.  (I’ve done FOUR IVF cycles, for goodness sakes!)  But if it does not work out, we will be okay, and incredibly, immensely grateful that we were able to have our (amazing, wonderful, perfect) one. 

That said, I’m feeling optimistic about this!  I’ll give an update in a couple weeks after the heartbeat appointment.
