I feel bad now. I did start of being nice and explaining there was nothing in the house (He said he heard noises upstairs) and that nothing could hurt him.
He is 10 btw!
He got upset and i ended up getting cross because he didn't want to go back to bed.
I handled it so badly.
He has gone up now but he had started crying.
I am sure there was a better way i should of dealt with it.
