Firefly, I think you should postpone your DH's appointment until you've given it some more thought. It sounds like you're not ready to finish your family and you don't want to do anything you'll regret. A couple of things to consider - I fell pg with no 2 while bfing DS, so you won't necessarily have to stop bfing to conceive. At some point your fertility will most likely come back, especially as your son increases his solids intake (and especially if he sleeps through the night without a feed). Also I was 35 having no 1 and will be (just) 37 having no 2. I too was worried about having kids this late but have had no complications. My personal limit now is 38 so I won't be having more, but I'm very glad I've gone back for seconds (although remind me I said this once I have a newborn again!!).

Best of luck with your decision.
