My dd is incredibly spoiled by my DM her grandma and when she visits (alone) over the summer holidays comes back very babyish. She is 12 and crying about wanting to sleep in our bed because of thunder.
Once she started secondary school I said no more sleeping in our bed. I just have the one and to be honest she still doesn't 'sleep through the night' at age 12. Mummy I want a drink of water, cold, wind, scary shadow. Typing this out now she seems insecure, but normally she is a really outgoing child.
