Grandparents: How many grandkids (and kids) do you have?

Ok I have 1 step grandchild 2 kids 3 step kids, but my mom had 10 kids and adopted 4 of us. really complicated but my adopted mom (who is my biological grandma) has I believe 173 decendants. Biologically speaking my birth mother had 4 kids and has 4 grandkids & 4 stepgrandkids. I don't count my oldest sister's girlfriend's kids in that. I have 2 of my own as said before 3 stepkids & my sister kathy has 2 kids & 1 stepson.
