Age between siblings.

Nikki
My husband and I have already been blessed with a wonderful son who's 6, will be 7 in September 2014. 
​We've been TTC for just over two years. Having baby #2 would be wonderful but obviously at this point there would be several years between the two. 
​Does anyone have two or more children already that have several years between them? Pros? Cons? Thoughts in general?
