We are incredibly lucky to have two healthy children conceived by IVF after many attempts. We also have three frozen embryos which are in good condition. I am tempted to try for a third child, and my partner is happy to, though he thinks financially it would be easier to stick at two. We could afford it with some lifestyle adjustments. However, I am in my mid 40's which can cause pregnancy and birth complications. Should we leave well enough alone and be thankful for our two healthy kids, or go for another little person?
