This is our third, and I'm almost positive it will be our last. From the moment DD2 was born, I knew I wanted another. 2 weeks later, DH said "at least one more, OK?". And from the moment I found out I was pg this time, I've been OVER IT. This pregnancy has a definite feeling of finality to it, so I'm pretty sure this will be it. Also, having been pregnant and/or nursing for almost the last 5 years, it's appealing to me to get my body back in...oh...just another three years!
