After posting a while back saying that I would be quite keen on having a third child and that DH was totally against the idea it looks like things have changed a little.
DH has just spent a week abroad alone and has come back and told me that that he had a lot of thinking time while he was over there and that he isn't 100% against having another child. It isn't a definite yes but certainly a step in the right direction for me.
He told me that his reasons for not wanting anymore were more about him: getting time back for himself and us as a couple, expense was another issue but not the be all and end all. He said he has thought a lot about how dds would be with another child in the house and how I would cope (found it hard not being able to give dd1 the attention I had done when dd2 was born, am also being treated for depression at the moment). He also said that we have room in the house for another. We are trying to move to America so timing isn't perfect at the moment anyway.
I have such mixed emotions right now.
