TO TRY OR NOT TO TRY, THAT IS THE QUESTION

Just when I think I've made my decision, doubt creeps back into my mind. Should we try for baby #3 or stop and enjoy the two we have? Since the youngest has been more of a handful than the first, we thought we had made up our mind about stopping and not having anymore. But then I see all these new babies and pregnant mommies and big families, that I wonder if we should go ahead and go for baby #3. Every day I list the pros and cons in the back of my mind. That's all I think about these days.

Pros:
1. A new baby to have and love.
2. Both kids want another sibling.
3. Both kids said they are willing to sacrifice extracurricular activities, vacations, and toys for the new baby. I love the unselfishness qualities they have. Makes me so proud.
4. Age difference: By the time the baby will be born, both older kids will be in full time school, so things wouldn't be so hectic timewise.
5. The older kids can help out.
6. I love the thought of a big family. My better half has a big family and I think that is so cool. I only have one brother and I always wonder what it would of been like to have another sibling. I see big families on vacations and it looks like so much fun.

Cons:
1. Sanity
2. Three kids and I only have two arms. One will always be getting away.
3. Less money to take vacations. We have taken the kids on numerous vacations. We love to travel and take the kids to fun places. We have taken the kids everywhere, from camping, to Las Vegas, to Disneyworld, to Seaworld, to family reunions in Minnesota, North Dakota, Ohio, and El Paso. And we would love to keep doing that.
4. Less time for extracurricular activities. Three kids in sports at the same time. Do I need to say more?
5. Finding a babysitter for three.
6. Starting over. Just when I'm getting used to diaper free kids, being able to sleep through the night, and kids being more independent and doing things for themselves and now I want to start over with sleepless nights, baby food, and stinky diapers?

I could think of more and more pros and cons, which makes my decision harder. If we decide to try, our point of no return is this summer. If we don't get pregnant by this summer then it wasn't meant to be. I don't want the age difference between the youngest and the new baby to be more than five years. I think any more than that would be too much. I just hope we decide whether or not to try before the deadline. Anyone else contemplating more than two kids? Anyone have advice or comments?
