Jeannie my grandson is 5 and we have the same issue. We solved it by making a brief video for him and his folks show him, sometimes we tell a silly joke, or anything to keep it interesting, but the video is addressed to him. He then makes a video in return, even if it is blowing a kiss and saying I love you. Or "stay in" or something. This is working well for all parties concerned. .
(Last week he progressed to writing a 'script' for his video and reading it out).
I realise your GD is a bit younger, but I hope my suggestion helps.
