We live 2000 miles or more away from grandparents. These boys only get to see them about annually. Definitely not as much as we'd like!
About a year ago, my mother-in-law had the brilliant idea to have "Grandma Nan Hangouts". At our designated time weekly (historically, Wednesday mornings; recently changed to Saturday afternoons) we sign into Google hangout.
For 30 minutes Grandma Nan reads the boys picture books.
For 30 minutes they sit on the couch enraptured by books with Grandma.
For 30 minutes, I have quiet time to start dinner, do my hair, or heck, shower.
It is a beautiful, beautiful thing: advancing gram/kiddo relationships, literacy and mommy hygiene.
