We have a wonderful 15 month year old son who we love to bits and are a very happy little family. The thing is we are now starting to wonder whether we should have another child or not. I had always taken for granted I would have at least 2 children but now not so sure. My DH and I both have troublesome relationships with our siblings and are now starting to wonder whether we should just stick to our DS. Not sure though if being an only child would be worse for him though - any thoughts? Advice much appreciated.
