My DD 2.3 years old seems to have an imaginary friend at nursery. The first time she stayed on her own she complained of a girl called Sarah hitting her. So I asked her teachers and there is no Sarah in nursery? They didn't seem aware of any incident. She kept telling me about it and today she mentioned her again but said they are friends now. Weird. She has excellent speech-can have proper conversations etc so I'm pretty sure I'm not mishearing her.
Is this common so young? I'm guessing it might be a way of coping with being without me there. I hope it doesn't mean she's unhappy.
