Little 'un is 4.5 and has until recently been going to bed on his own ok, settling down and going to sleep (sometimes creeping into our bed in the middle of the night).
The last couple of nights he had been going on about green aliens and being afraid and not liking his room. He is fine if he jumps into our be by himself, then decanted into his own bed when we go to be.
We both have rotten colds and sinusitus and it is hard to be sympathetic after a long day...!
Any suggestions on getting him to believe us that they don't exist and that nothing is going to 'get him' and that we are here to 'protect him'.
