Well we are in the TPR process for sibling group of 4 and have 1 other FS that we are in the process of adopting.
All total we have 9( one of our bio sons

passed away 3 years ago).We need a 15 passenger van,we have just started looking for one.We use to take 2 cars but since this has truned into adoting we are going to do a more permanet thing.
WE have 4 girls in one room,the 2 little boys in a room ,the baby with us and our 18yo gets his own room.
I do not think we are done GOD has not put that filling in my heart yet.We to live basicly pay check to pay check and I stay home with the children.Do not feel guilty about wanting more,you want what your heart wants and as long as you can love them then I say go for it!!!!
If you really are meant to have a big family then it will happen!
