DD is 2.5 and the latest development in our long saga of getting her to bed is that there's someone in her bedroom! There's a definite change in her behaviour at bedtime and she seems genuinely upset to go into her room.
I put this down to having watched Monsters Inc for the first time the other day and we've had problems since! She's not usually frightened of anything (she laughs at the shark in Finding Nemo) and I think most children go through this stage.
Will we be digging a huge hole for ourselves if we sit in her room until she goes to sleep or should we just stick to our guns and tell her there's no-one there?
