My son is 6 months is it to early to be trying again?

I think that determining if it is too soon or not is a personal decision and depends on your life and how close you want your children to be, my children are 17 months apart and seem to get along great but at the same time my oldest is a little too young to understand that when baby brother is crying that I have to stop reading her her book or whatever else we are doing and tend to him and that definitly adds to the stress too. I woudl say just have sex every few days and you should be able to hit when you are most fertile. That was how we ended up conceiving our youngest.. although I wouldnt say he was exactly planned we just werent doing anything to prevent it either.. good luck =)
