I can see his point when he is comparing me to many others who haven't been fortune like me to have a larger then average family and despite many pregnancies I still have 3 very healthy happy children but on the other hand if my DH and I want more children and are paying for a service (IVF) provided we fit their criteria which we would who is it to decide we shouldn't try for another through IVF because we already have 3. If we didn't have any together but I had 3 for example I am sure he would see that as a reasonable request but not because we have children together. I don't have to worry about that now anyway and am so fortunate age is currently on my side so I have a few years left before making that decision anyway.
