My 18 month-old girl has been acting very strangely around my grandmother (who is like my mum to me)who lives far away from us. My daughter 'talks' to my gran all the time when she is not with us on an imaginary phone and is full of smiles for her when she arrives to visit but won't let her touch her and gets very agitated, calling for me constantly. My gran is so in love with her that it's heartbreaking. She is not forcing herself on her to try to make things better but she is very upset. Any advice or similar experiences?
