At age 34, am I crazy to wait and try for due date based on school year?

I am 34 and we currently have no children. I have read numerous articles that indicate that the youngest children in the class are at a significant disadvantage to the older ones. DH and I could begin TTC very soon, but I am contemplating waiting until December. This would mean should we conceive, the due date would be at earliest September resulting in our child being one of the older ones. That being said, I totally accept the things out of my control so should it take us 10 months to conceive and my child ends up being one of the youngest in the class, I don't mind. I just wondered if I shouldn't be delaying things for 7 months given my age and the reason for it?

I started TTC at your age and it took almost two years. You'd be silly to put it off for this reason. If you start trying and you aren't pregnant after 9months are you going to stop again to avoid the following summer months too?
