We have 7 and thought we were done after 6, but plans change. A friend of my sister's and her teenage daughter approached us about adopting her daughter's baby and it just felt right! She was born a month ago and has been such a blessing to our family! So I won't say we're done, I'll say if our family is meant to be complete with 7, we'll be happy and if we are meant to expand again we'll be happy :).
Nope, I'm done having babies. I figure even after all my kids are out of the baby and toddler stages I can always go play with my friend's babies and I've got younger siblings who I expect will someday have babies that I can spoil.
