When I was 3 we moved house. We went from a small housing estate to a cul de sac with 3 houses.
All the kids used to play out in the estate even 3 year olds. It was a small safe estate, one road in/out always a parent watching & it's was the 70's…
Anyway with in 3/4 days I was chatting about playing with the little girl from next door. As the neighbours one side were in their 60's and the other side a family with 3teen/just preteen boys parents decided it was a imaginary friend/ reaction to moving.
She never had a name but I described her as having long ringy (ringlet) hair and a flowery bridesmaid dress. Mum found this funny, as a little girl I refused to wear dresses.
Anyway eventually I went to school and I stopped mentioning her.
Here's where it gets woo, a few months after I stopped talking about little girl next door (lgnd) my little sister was born. When she was 2 and a half she started talking about her new friend… the little girl next door. Mum & Dad swear they couldn't recall ever mentioning it in front of her.
2nd little sister was a year younger and at one point both of them were 'playing' with her.
So rational explanation is my imaginary friend, little sis's overheard and carried it on.
Till my cousin visited from Oz with her little girl. Who spend the afternoon playing in the garden playing with the little girl next door. It was cousins first visit to the 'homeland' her parents had been estranged from the family so no way it could have been a family story.
Freaked Mum out, well all of us a bit, but in a nice way, apparently she'd fall out with each of us /tell us off if we were being naughty.
Mum looks after my niece 2 days a week, she's going to turn 2 soon…
