Talking to either Grandpa or Grandma
My Grandpa is passed away, and my husband's Grandma is passed away also. I will hear my daughter over the baby monitor talking and laughing so much I will hear her say "Papa." or "Grama." every now and then. And when I go into her room she'll be looking at a fixed point or the rocking chair or until her attention is on me. I have seen several different things here that make me believe she is talking to them.
