Kirsty - I think Kell's right... imagine how much more tired and stressed you would be with another baby, especially if (god forbid) you did have another premmie. If you don't feel ready then you're not ready - and I don't think that's being selfish at all. As for another baby helping Gussy's development, do you take him to a playgroup or mums group? I find with Dylan that just having him watch all the other babes crawling and standing inspires his development. In fact, the first time he crawled properly was 2 hours after we had a playgroup at my house where all the other babies were able to "climb" up the step to our dining room and he was left behind...
