The short answer? WHATEVER WORKS FOR YOU is the right thing to do. :) That being said, I am one of the few that likes having my boys farther apart. For many years (even before we had kids), we both thought we only wanted one child. Then a couple years ago, we started thinking along the lines of a fuller family, a sibling for #1, etc. My boys are exactly 3 1/2 years apart, and we love the gap. I was able to shephard my first through the baby years without rushing him out of a crib or highchair. I felt like I could really relish our time together. Now, with my second (who is 5 mo.), I appreciate that my older son is more self-sufficient. Can go to the bathroom by himself, is in preschool, can entertain himself, fill his own water, etc. He's so busy growing up, it helps keep his mind off the time I spend with the baby. I think he also better understands what babies are all about, which helps me feel more secure in their own relationship. I used to worry if they'd play together, being so far apart, but my (almost) 4 year-old loves his brother, and is happy to play peek-a-boo, etc. And soon enough, I know they will be sharing other things, most of all time together. It's not an easy decision, I know. But you'll come up with something and before you know it, you'll be a family of 4 and it will feel so right!
