For me personally I knew deep down that my family wasn't finished at two.

I always said that we'd see how we go in regards to how many children we end up with. When people ask I tell them that I'm not sure if this will be our last child. I'm not saying that there will definately be a fourth child for us at this point in time, but if people have the need to ask me, that is what I tell them.

I don't think that makes me unsatisfied with the children I already have.
