Charlie was saying he missed his grandma, so we called her... but then he didn't really have much to say. He just doesn't seem to "get" how the phone works! Plus, he gets a little shy when the conversation starts...
I was wondering if maybe Facetime or Skype would work better for him... maybe being able to see someone would make it feel more real to him? Haven't been able to test that theory out though, since grandma doesn't have an iPhone... and Skype isn't installed on her Android. Same goes for his friends' parents...
Is your LO good on the phone? How about Skype or Facetime?
