How to get over wanting #3!?

mumma of two

I am very blessed to have two beautiful healthy kids &I; a supportive (almost husband). We had our son 2 months ago and are set to be married in February. My fiancé is dead against having another baby, but me on the other hand still wants another. The way I look at it we've got at least another 20 years in my baby making factory.

The yearning is so strong. How did you all move past this?
