Congrats on your soon to arrive grandkid! :) I have only two grown children as of yet, but I hope the upcoming four will give me lots more grandbabies.
I think all my kids will homeschool. My second oldest just taught her daughter to read; she is not quite four. My daughter's in-laws are amazed but think that the granddaughter will still have to go to public school when she turns five. Obviously they don't get it!
