Jenny, a Mother of two, wonders how you really know when you've reached your limit.

I feel very blessed to have two healthy, beautiful, "perfect" little girls (ages 3 and 6). I always knew that I wanted two children. I come from a family of four (as does my husband) and it seemed only natural to have two children. With that said...Now that my kids are getting to an age where they are becoming a little more independent, my husband and I have begun to contemplate whether or not to have a third child.

I am someone who pretty much over-thinks and researches everything in my life to confirm that I'm making the right decisions, so this was no exception. I am constantly questioning my friends. Many of them have three or more kids and love the chaos.

Some say that now, while their kids are young, things tend to be hectic, but they often look to the future and think how nice it will be to have a big family. Several others feel their family is complete after two children and they are thrilled to be moving on with their lives. Then, there are some of us who are uncertain where to go from here. Am I done with this stage of my life?

Do I give away the crib, maternity clothes, breast pump? I don't know if I am ready to part with this stage. I love being a Mom and my kids are growing up so fast. They're out of diapers, can dress themselves and will both be in school full-time come September. This should be a time to celebrate my independence a little, right? Some days I am celebrating the fact that I can shower in the mornings and make it to the gym every day (if I was so motivated). Other days I am missing baby hands wrapping around my finger, those little wrists that look as though they have rubber bands wrapped around them, the way they smell when they are just bathed.

Most people think that if you are not certain that you're "done," then you're not. It would make things a lot easier if my husband felt strongly one way or the other, but he pretty much feels as I feel---ambivalent. Parents face so many challenges with their kids these days. I have seen many of them having been a special education teacher prior to having kids. Are we asking for too much to desire a third "healthy" child? Could we even balance three kids in our life?

When we go into our children's room at night and watch them sleep, or cuddle with them while reading a bedtime story, we look at each other and think "We can do this again." There are also those days when they are fighting and whining, and get out of bed throughout the night and we are completely sleep deprived and we think "We can't do this again."

Like I said, I'm a researcher, so I sought my doctor's advice. I spoke with her about my uncertainty and she suggested that we just "give it a shot" and if it happens it's meant to be, and go from there. I love her candidness! So, guess what? We followed her advice. And guess what? We got pregnant! Didn't expect that--Did you? Guess it was meant to be! Well...not really, I miscarried. Now what? Is that a sign that I am done? Or, because we were sad when we lost the pregnancy, is that a sign that we really want a third? Where do we go from here? Do we try again? Are we done yet? Who knows!!!
