For example, we used to be able to raise our voice and the kids could hear us from any room in Widney Loft. Now that we are on two floors and every room has walls that go all the way to the ceiling in Widney Crib, we NEED an intercom.
We have used the kids' iPods to FaceTime or text with them. They prefer to contact us that way as well. J found an intercom app that let's us communicate via our wifi. It's pretty awesome.
