Good Day,
I have always taught my son & now 2 little nieces that the only monsters are people in make-up. For some reason, teaching them all this has worked! I explain that it is just like when Mommy puts on face make-up, it is just a different look. I've put on make up to make a funny face and for unknown reason- they quit being afraid. Unconventional I am sure- but it has worked 3 times now! Good luck!
