I have 3DC under 7. For a while now we have been seeing a small figure dashing down the corridor in our house and passing by doorways. Often when my three DC come into my bedroom in the morning it is behind them or amongst them. They also see it. Seems to be fondest and following around my middle child (he's 6.) Quite often in the morning (she) will come into the bedroom with him and I'll think it's my actual 7 year old, then she shadow will run into a wall.
Is this something I need to be worried about? Do child ghosts like being with other children?
