I want another one...

Ha
This may be a bit crazy but I really want to try for another baby sooner rather than later. My little one is six weeks old don't get me wrong I'm not saying right now but maybe in a couple of months. Anyone else have any expierience of having babies close in age? There is only 14 months between me and my brother and we always got on so well as kids, I would love the same for my little boy.
