am I crazy?

because I feel like I want to have another baby...just looking at the girls growing up so fast makes me want just 1 more! I know that the risks are just too great for another pregnancy which is my logical side talking...but my emotional side thinks it might work out just fine like with the girls. I remember after I had Emma and Lily and they were in the NICU one of the neonatalogists who also took care of baby Jack said that when they found out we were pregnant they all said a prayer for us...and when they found out it was with twins they all got down on their knees in prayer for us knowing that it was a very high risk situation. I know that my twin girls are a total miracle in that they made it 32 weeks and have NO health or significant developmental delays. If only I didn't have: a blot clotting disorder and a incompetant cervix--then I would have like 10 kids...but 2 (and 1 in heaven) is perfect too. Jen
