Please talk me out of it.

We hve two beautiful, perfect, healthy children, and I feel blessed every day for that. Suddenly, despite years of saying I wanted no more than 2, I am actually considering a third. My husband would populate the earth with children if I let him, but pregnancy and early babyhood have always been .... tough for me. I honestly don't know if our marriage could survive it again. However, my heart is suddenly getting the better of me, and I am finding myself really wanting another one, despite all the reasons I had cited before: the $$, especially child care, the fact that our youngest is actually showing signs of FINALLY being out of diapers, we want to travel, they actually listen to me (sometimes) when I ask them to do things, and finally, the fact that I refuse to drive a minivan.

But, the whole getting pregnant/planning for new baby/excitement thing is suddenly calling to me again, and I am forgetting all that other stuff. I am certain that DH would be thrilled at the idea that I am even considering it, so I am of course hesitant to talk to him about it ....  don't know. Talk me out of it, please. Three kids is horrifyingly difficult, isn't it????
