Surprise pregnancy, with surprise twins!!

Today we found out that our twins are a boy and a girl, and we couldn't be happier. After having 4 kids, 3 girls and then finally our boy, we had decided to be done. Then Thanksgiving morning we found out that we pregnant, and then a week later we learned there were two growing within me! What a shock! But I have been in love with them since the moment we found out. We are so excited. Any advice from moms out there with 6 kids?!?! We are so blessed!!!
