My 4 year old daughter has developed a strong friendship with a girl in her class. They went in to class everyday holding hands, so excited to see each other. Then when school finishes they wait for each other to walk out of school together. But over the past two weeks my daughter has appeared really excited to see her friend but then when she comes closer she pulls her hand away, refuses to hug her, hides behind me sometimes and is generally avoidant most of the time. She says she is still her friend and she seems excited to see her every morning and afternoon but then turns like that. I'm worried about it upsetting her friend and her loosing the friendship. Any advice/stories welcome 🙃
