I had my oldest when I just turned 25 and my youngest when I turned 38. I can honestly tell you there are pros and cons to both! I had SO much patience when I was young. But, now that we are older, we can actually afford this fourth child! Being older, if you're a career person, you might feel like you've "been there, done that" as far as your career is done and can focus on your child, whereas if you're young, you might always have that "itch" to get back to work and not devote yourself 100% to being a parent (if your desire is, in fact, to be a stay-at-home mom). When you're older, I think you appreciate this special, very precious gift a bit more because you've seen and experienced so much more, and witnessed a lot of things so that you can truly understand what you're holding in your arms, and what a gift it is. I feel almost like I kind of grew up along with my oldest two kids (was 25 and 27 at the time of their birth), but with my younger two, I feel like I let things go much more, don't worry about the little things, and enjoy them fully (although the lack of patience can sometimes get to me!!!).
