A.N.
I am in the same boat, my son is 4 and we have been talking about another kid, after a long time of thinking one was enough. I would really like to do it soon, but I have a big race in May, and some other trips and things I want to do before being pregnant, so I need to wait at least 7 months. I don't want to wait any longer for a few reasons, I will be at least 32 when I have my next one (not super old for pregnancy, but I still worry), and I think over 6 years is a bit too long of a separation between kids. I have a brother who is 4 years younger than me, we are super close, but my sister is 9 and a half years younger than me, and we are so far apart, with nothing in common,we aren't even really friends now that she is in her 20s. I think at around 7 years you hit that point where it is harder for them (it sounds like that from the other posts as well). I say go for it sooner rather than later.
