I have 4 year old twin girls. They are about as different as they can be in looks and personality.
One of my girls has a vivid imagination. A few months ago she started discussing her "other mother" (not mummy, not mum always Mother). She said she had purple rainbow hair and lived in the woods. She would often say her Other Mother baked her cakes and played with her and she was so much fun 🤔
We've now moved on to her Giant Sister who lives with her other mother in the woods. I don't always encourage it as such but I always kind of say wow that's amazing etc.
Is this something to be worried about or do I just let her discover her imagination and just roll with it?
